[Fontconfig] Build failure with MinGW/2.10.92

[Josh]

I am no longer able to build fontconfig on MinGW:

This is the first time I ever had problems with fontconfig. I link it 
with MPlayer, apparently the mingw.org toolchain doesn't have 
"_MKTEMP_S" yet it worked fine before without it so why is _MKTEMP_S 
required now?

I can't switch to MinGW-w64 for MPlayer even though it's more updated 
and probably has it, I would like to, but I run endlessly into even more 
errors with MPlayer on those toolchains..
