In Git for Windows' SDK, the tests are run using a Bash that relies on
the POSIX emulation layer MSYS2 (itself a friendly fork of Cygwin). As
such, paths in tests can be POSIX paths. As soon as those paths are
passed to git.exe (which does *not* use the POSIX emulation layer),
those paths are converted into Windows paths, though. This happens
for command-line parameters, but not when reading, say, config variables.
To help with that, the `pwd` command is overridden to return the Windows
path of the current working directory when testing Git on Windows.
However, when talking to anything using the POSIX emulation layer, it is
really much better to use POSIX paths because Windows paths contain a
colon after the drive letter that will easily be mistaken for the common
separator in path lists.
So let's just use the $PWD variable when the POSIX path is needed.
This lets t7800-difftool.sh, t9400-git-cvsserver-server.sh,
t9402-git-cvsserver-refs.sh and t9401-git-cvsserver-crlf.sh pass in Git
for Windows' SDK.
Note: the cvsserver tests require not only the `cvs` package (install
it into Git for Windows' SDK via `pacman -S cvs`) but also the Perl
SQLite bindings (install them into Git for Windows' SDK via
`cpan DBD::SQLite`).
This patch is based on earlier work by 마누엘 and Karsten Blees.

We did it differently, after all, before contributing the patches
upstream that make the test suite pass on Windows (see "mingw: fix
t5601-clone.sh").

Since baaf233 (connect: improve check for plink to reduce false
positives, 2015-04-26), t5601 writes out a `plink.exe` for testing that
is actually a shell script. So the assumption that the `.exe` extension
implies that the file is *not* a shell script is now wrong.
Since there was no love for the idea of allowing `.exe` files to be
shell scripts on Windows, let's go the other way round: *make*
`plink.exe` a real `.exe`.
This fixes t5601-clone.sh in Git for Windows' SDK.

`GetLongPathName()` function may fail when it is unable to query
the parent directory of a path component to determine the long name
for that component. It happens, because of it uses `FindFirstFile()`
function for each next short part of path. The `FindFirstFile()`
requires `List Directory` and `Synchronize` desired access for a calling
process.
In case of lacking such permission for some part of path,
the `GetLongPathName()` returns 0 as result and `GetLastError()`
returns ERROR_ACCESS_DENIED.
`GetFinalPathNameByHandle()` function can help in such cases, because
it requires `Read Attributes` and `Synchronize` desired access to the
target path only.
The `GetFinalPathNameByHandle()` function was introduced on
`Windows Server 2008/Windows Vista`. So we need to load it dynamically.
`CreateFile()` parameters:
`lpFileName` = path to the current directory
`dwDesiredAccess` = 0 (it means `Read Attributes` and `Synchronize`)
`dwShareMode` = FILE_SHARE_READ | FILE_SHARE_WRITE | FILE_SHARE_DELETE
(it prevents `Sharing Violation`)
`lpSecurityAttributes` = NULL (default security attributes)
`dwCreationDisposition` = OPEN_EXISTING
(required to obtain a directory handle)
`dwFlagsAndAttributes` = FILE_FLAG_BACKUP_SEMANTICS
(required to obtain a directory handle)
`hTemplateFile` = NULL (when opening an existing file or directory,
`CreateFile` ignores this parameter)
The string that is returned by `GetFinalPathNameByHandle()` function
uses the \\?\ syntax. To skip the prefix and convert backslashes
to slashes, the `normalize_ntpath()` mingw function will be used.
Note: `GetFinalPathNameByHandle()` function returns a final path.
It is the path that is returned when a path is fully resolved.
For example, for a symbolic link named "C:\tmp\mydir" that points to
"D:\yourdir", the final path would be "D:\yourdir".

This topic branch squashes the annoying compiler warning claiming that
`dirname()` was not declared.
For some strange reason, changing `basename()` to conform to POSIX does
not re-introduce https://github.com/git-for-windows/git/issues/494. This
developer assumes that the problem in the test suite were somehow fixed
in the meantime, but lacks the time to verify that claim...

Unfortunately, some libgen implementations yield outcomes different from
what Git expects. For example, mingw-w64-crt provides a basename()
function, that shortens `path0/` to `path`!
So let's verify that the basename() and dirname() functions we use conform
to what Git expects.

When there is no `libgen.h` to our disposal, we miss the `dirname()`
function.
So far, we only had one user of that function: credential-cache--daemon
(which was only compiled when Unix sockets are available, anyway). But
now we also have `builtin/am.c` as user, so we need it.
Since `dirname()` is a sibling of `basename()`, we simply put our very
own `gitdirname()` implementation next to `gitbasename()` and use it
if `NO_LIBGEN_H` has been set.

Junio Hamano pointed out that there is an implicit assumption in pretty
much all the code calling has_dos_drive_prefix(): it assumes that the
DOS drive prefix is always two bytes long.
While this assumption is pretty safe, we can still make the code more
readable and less error-prone by introducing a function that skips the
DOS drive prefix safely.

When git.rc is compiled into git.res, the result is actually dependent
on the architecture. That is, you cannot simply link a 32-bit git.res
into a 64-bit git.exe.
Therefore, to allow 32-bit and 64-bit builds in the same directory, we
let git.res depend on GIT-PREFIX so that it gets recompiled when
compiling for a different architecture (this works because the exec path
changes based on the architecture: /mingw32/libexec/git-core for 32-bit
and /mingw64/libexec/git-core for 64-bit).

Commit 4b623d8 (MSVC: link in invalidcontinue.obj for better
POSIX compatibility, 2014-03-29) introduced invalidcontinue.obj
into the Makefile output, which was not parsed correctly by the
buildsystem. Ignore it, as it is known to Visual Studio and,
there is no matching source file.
Only substitute filenames ending with .o when generating the
source .c filename, otherwise a .cbj file may be expected.
Split the .o and .obj processing; 'make' does not produce .obj
files.
In the future there may be source files that produce .obj files
so keep the two issues (.obj files with & without source files)
separate.

Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
To be precise: when the value of the environment variable is shorter than
its name, we have to move the remaining bytes *after* expanding the
environment variable: we would look for the wrong name otherwise.
When the value is longer than the name, we still need to move the bytes
out of the way first, to avoid overwriting them with the interpolated
text.

Git for Windows 2.x ships with an executable that starts the Git Bash
with all the environment variables and what not properly set up. It is
also adjusted according to the Terminal emulator option chosen when
installing Git for Windows (while `bash.exe --login -i` would always
launch with Windows' default console).
So let's use that executable (usually C:\Program Files\Git\git-bash.exe)
instead of `bash.exe --login -i` if its presence was detected.
