Re: [Patch, libgFortran] Fix MinGW64 compile warning

Since the reason for adding the gfstat_t typedef was that on mingw we
needed to use struct _stati64 instead of struct stat, and that
justification now seems to be gone with this patch, please also remove
gfstat_t and just use struct stat everywhere.

How about the attached patch? (Build & regtested on x86-64-linux.)

2011-04-04  Tobias Burnus  <bur...@net-b.de>

	* unix.c: Adapt stat DEFINEs since MinGW64 supports LFS.
	(fallback_access, open_internal4, compare_file_filename,
	find_file, file_size, inquire_sequential, inquire_direct,
	inquire_formatted): Use "struct stat" instead of gfstat_t.
