From: Sibi Siddharthan <sibisiddharthan.github@xxxxxxxxx>
This patch facilitates building git on Windows with CMake using MinGW
NOTE: The funtions unsetenv and hstrerror are not checked in Windows
builds.
Reasons
NO_UNSETENV is not compatible with Windows builds.
lines 262-264 compat/mingw.h
compat/mingw.h(line 25) provides a definition of hstrerror which
conflicts with the definition provided in
git-compat-util.h(lines 733-736).
To use CMake on Windows with MinGW do this:
cmake `relative-path-to-srcdir` -G "MinGW Makefiles"
