re PR libfortran/23272 ([mingw32] inquire via filename fails)
PR libfortran/23272 * acinclude.m4 (LIBGFOR_CHECK_WORKING_STAT): New check. * configure.ac: Use LIBGFOR_CHECK_WORKING_STAT. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * config.h.in: Regenerate. * configure: Regenerate. * io/unix.c (compare_file_filename): Add fallback case for systems without working stat. * io/open.c (already_open): Correct call to compare_file_filename. * io/io.h: Correct proto for compare_file_filename.
