PATCH win32/mingw32: jcf_open_exact_case prototype

[Aaron W. LaFramboise]

I've been applying the following patch to fix a no previous prototype
warning that causes bootstrap to fail at werror.  Including the header
that prototypes jcf_open_exact_case causes lots of undefined symbol
warnings, and so it seems this is not the way to do this, so I just
simply prototype the function near the other file prototypes.

I don't know if this is the right way to fix this warning.
