--- Comment #11 from Tobias Burnus <burnus at gcc dot gnu.org> 2011-03-02 17:03:47 UTC --- (In reply to comment #9) > It seems that MinGW has its own implementation of snprintf called > __mingw_snprintf which can be activated by defining __USE_MINGW_ANSI_STDIO In MinGW64, __USE_MINGW_ANSI_STDIO is set when _POSIX is specified. In MinGW that does not seem to be the case and one needs to specify it either directly or use another define such as _POSIX_SOURCE. Cf. http://cygwin.com/cgi-bin/cvsweb.cgi/src/winsup/mingw/include/_mingw.h?rev=1.61&cvsroot=src >From libgfortran/libgfortran.h: #if defined __MINGW32__ # define _POSIX 1 # define gfc_printf gnu_printf #else
