Re: [Vala] why valac says "error: Failed to execute child process (Exec format error)"

 $ file $(which valac)
/opt/windows_32/vala-my-build/bin/valac.exe: PE32 executable for MS
Windows (console) Intel 80386 32-bit

$ file $(which  pkg-config)
/opt/windows_32/bin/pkg-config.exe: PE32 executable for MS Windows
(console) Intel 80386 32-bit

$ file $(which gcc)
/opt/windows_32/bin/gcc.exe: PE32 executable for MS Windows (console)
Intel 80386 32-bit

$ file /e/msys/opt/windows_32/bin/libglib-2.0-0.dll
/e/msys/opt/windows_32/bin/libglib-2.0-0.dll: PE32 executable for MS
Windows (DLL) (console) Intel 80386 32-bit

and this is a test on a 64bits application for comparation:
$ file /e/greensoft/3d/blender/blender-2.77.1-git.9d431f1-AMD64/blender.exe
/e/greensoft/3d/blender/blender-2.77.1-git.9d431f1-AMD64/blender.exe:
PE32+ executable for MS Windows (console) Mono/.Net assembly
