Hello,
 I build git on msys environment regularly. With the recent changes to
add cache preload facility (commit ID:
671c9b7e315db89081cc69f83a8f405e4aca37bc) brings in dependency on
pthreads. This is not available in the msys distribution which was
part of the git build distro. I installed libpthread for mingw to get
the related headers and libraries. I had to make some minor changes to
libpthread installation. I copied the 'setjmp.h' from my other mingw
installation and had to had edit it to remove some mingw specific
macros.

Also,
 had to copy a pthread library with a dfferent name to the standard name:
$cp libpthreadGC2.a libpthread.a

The build went fine and am using the new binaries.
