re PR libfortran/23138 ([mingw32] real(16) values are printed incorrectly)
PR libfortran/23138
* acinclude.m4 (LIBGFOR_CHECK_MINGW_SNPRINTF): New check.
* configure.ac: Use LIBGFOR_CHECK_MINGW_SNPRINTF.
* libgfortran.h: If HAVE_MINGW_SNPRINTF is true, use __mingw_snprintf
instead of snprintf.
* config.h.in: Regenerate.
* configure: Regenerate.
