During an MSVC build on cygwin, the make program did not notice
when the compiler or linker exited with an error. This was caused
by the scripts exiting with the value returned by system() directly.
On POSIX-like systems, such as cygwin, the return value of system()
has the exit code of the executed command encoded in the first byte
(ie the value is shifted up by 8 bits). This allows the bottom
7 bits to contain the signal number of a terminated process, while
the eighth bit indicates whether a core-dump was produced. (A value
of -1 indicates that the command failed to execute.)
The make program, however, expects the exit code to be encoded in the
bottom byte. Futhermore, it apparently masks off and ignores anything
in the upper bytes.
However, these scripts are (naturally) intended to be used on the
windows platform, where we can not assume POSIX-like semantics from
a perl implementation (eg ActiveState). So, in general, we can not
assume that shifting the return value right by eight will get us
the exit code.
In order to improve portability, we assume that a zero return from
system() indicates success, whereas anything else indicates failure.
Since we don't need to know the exact exit code from the compiler
or linker, we simply exit with 0 (success) or 1 (failure).

In the MSVC section of the Makefile, BASIC_CFLAGS is set to a
value which contains the string "-DWIN32-D_CONSOLE". This results
in a (single) malformed -Define being passed to the compiler.
At least on my cygwin installation, the msvc compiler seems to
ignore this parameter, without issuing an error or warning, and
results in the WIN32 and _CONSOLE macros being undefined. This
breaks the build.
In order to fix the build, we simply insert a space between the
two -Define parameters, "-DWIN32" and "-D_CONSOLE", as originally
intended.

These scripts generate projects for the MSVC IDE (.vcproj files) or
QMake (.pro files), based on the output of a 'make -n MSVC=1 V=1' run.
This enables us to simply do the necesarry changes in the Makefile, and you
can update the other buildsystems by regenerating the files. Keeping the
other buildsystems up-to-date with main development.
The generator system is designed to easily drop in pm's for other
buildsystems as well, if someone has an itch. However, the focus has been
Windows development, so the 'engine' might need patches to support any
platform.
Also add some .gitignore entries for MSVC files.

Enable MSVC builds with GNU Make by simply calling
make MSVC=1
(Debug build possible by adding DEBUG=1 as well)
Two scripts, clink.pl and lib.pl, are used to convert certain GCC
specific command line options into something MSVC understands.
By building for MSVC with GNU Make, we can ensure that the MSVC
port always follows the latest code, and does not lag behind due
to unmaintained NMake Makefile or IDE projects.

Centralize the include of windows.h in git-compat-util.h, turn on
WIN32_LEAN_AND_MEAN to avoid including plenty of other header files
which is not needed in Git. Also ensure we load winsock2.h first,
so we don't load the older winsock definitions at a later stage,
since they contain duplicate definitions.
When moving windows.h into git-compat-util.h, we need to protect
the definition of struct pollfd in mingw.h, since this file is used
by both MinGW and MSVC, and the latter defines this struct in
winsock2.h.
We need to keep the windows.h include in compat/win32.h, since its
shared by both MinGW and Cygwin, and we're not touching Cygwin in
this commit. The include in git-compat-util.h is protected with an
ifdef WIN32, which is not the case when compiling for Cygwin.

A command line
$ git archive -o my-v2.0.zip v2.0
almost certainly wants the output in zip format, even though it does not
specify any --format option.
When --format is not given, but output filename is, try to infer what
format is requested from the filename extension. Currently this code only
knows about '.zip'. When the format is unspecified and the filename does
not tell us, the output will be in 'tar' format as before.
Of course, an explicit --format will not trigger this guesswork.

A local clone without hardlinks copies all objects, including dangling
ones, to the new repository. Since the mtimes are renewed, those
dangling objects cannot be pruned by "git gc --prune", even if they
would have been old enough for pruning in the original repository.
Instead, preserve mtime during copy. "git gc --prune" will then work
in the clone just like it did in the original.
