MinGW set the _CRT_fmode to set both the default fmode and
_O_BINARY on stdin/stdout/stderr. Rather use the main()
define in mingw.h to set this for both MinGW and MSVC.
This will ensure that a MinGW and MSVC build will handle
input and output identically.
Alexey Borzenkov:
Include git-compat-util.h from the test-genrandom.c so
that the application also will use the main() define,
and thus the stdout mode is set correctly and generated
data stays the same.
Johannes Sixt:
Before, since the test-genrandom application would link
against libgit.a, the MinGW process initialization code
would pick up the definition of _CRT_fmode from mingw.c
that is initialized to _O_BINARY. After this patch,
however, the _CRT_fmode symbol is no longer present in
libgit.a, so MinGWs process initialization code will not
set the correct std(in|out|err) mode. So, the include is
needed to override main() and explicitly set the mode.

Gaaaaah! Sorry for not reading Alexey's patch properly.
Multitasking is not working to my advantage these days..
