winsup/mingw CVS HEAD

[Earnie Boyd]

Danny has merged his branch into the CVS HEAD.  The MinGW runtime now
supplies many C99 compliances.  I will be uploading a mingw-runtime-2.0
version shortly.  In the meantime the HEAD is to be considered frozen
until I get out the release, hopefully today.  

If you wish to use the C99 extensions (extensions to the MSVCRT) then
you must add -lmingwex to the build line.
