Ramsay Jones	b5d18b8e6f	Fix the exit code of MSVC build scripts on cygwin 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).

Marius Storm-Olsen	259d87c354	Add scripts to generate projects for other buildsystems (MSVC vcproj, QMake) 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.

Marius Storm-Olsen	a2c6bf0e76	Add README for MSVC build Based on original README patch from Frank Li, describe the steps to build git with VS2008 (aka MSVC).

Marius Storm-Olsen	164a5e3faa	Add MSVC to Makefile 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.

Frank Li	16fe1e0369	Add MinGW header files to build git with MSVC Added the header files dirent.h, unistd.h and utime.h Add alloca.h, which simply includes malloc.h, which defines alloca().

Marius Storm-Olsen	55fcb06482	Add empty header files for MSVC port MSVC lacks many of the header files included by git-compat-util.h; add blank header files for these instead of going ifdef crazy.
