Summary:                    Compiling CMake with gcc under MinGW-64/MSYS on
64-bit Windows
Description: 
Changes (see attached patch):

(1) Added code to read HOME environment variable (to get MSYS root) and read
/etc/fstab (to get MinGw-64 path and other fstab entries) to map MSYS paths to
Windows paths.

(2) Added calls to "ConvertToOutputPath" where Windows API file system calls are
made.

(3) Minor changes to handle MinGw-64 C library differences from MinGw.

(4) There are still a few test failures. Some of the MSYS tools do not handle
the Windows paths with forward slashes generated by CMake. For paths used as
arguments to MSYS programs, there needs to be a way in CMake files to request
returning an MSYS path (e.g. /C/foo) instead of a Windows path with forward
slashes (e.g. C:/foo).

Example:

Fails:

cd /C/work/sources/cmake-2.8.7/Tests/ExternalProject/CMakeExternals/Source &&
/C/msys/bin/cvs.exe -d
C:/work/sources/cmake-2.8.7/Tests/ExternalProject/LocalRepositories/CVS -q co
"-D2009-06-26 16:50:00 UTC" -d TutorialStep1-CVS-20090626 TutorialStep1

Works:

cd /C/work/sources/cmake-2.8.7/Tests/ExternalProject/CMakeExternals/Source &&
/C/msys/bin/cvs.exe -d
/C/work/sources/cmake-2.8.7/Tests/ExternalProject/LocalRepositories/CVS -q co
"-D2009-06-26 16:50:00 UTC" -d TutorialStep1-CVS-20090626 TutorialStep1


The following tests FAILED:
         25 - FindPackageTest (Failed)
         99 - ExternalProject (Failed)
        132 - CTest.UpdateSVN (Failed)
        133 - CTest.UpdateCVS (Failed)
        134 - CTest.UpdateHG (Failed)

(5) Since MinGW-64 can be used on Linux to cross-compile for Windows, these
changes need to be tested there as well.
