...nough. What about this version -- int flac_snprintf(char *str, size_t size, const char *fmt, ...) { va_list va; int rc; va_start (va, fmt); #if defined _MSC_VER rc = vsnprintf_s (str, size, _TRUNCATE, fmt, va); if (rc < 0) rc = size - 1; #elif defined __MINGW32__ && (!defined __USE_MINGW_ANSI_STDIO || __USE_MINGW_ANSI_STDIO == 0) rc = vsnprintf (str, size, fmt, va); if (rc < 0 || rc == size) { rc = size - 1; str [rc] = '\0'; /* assert(size > 0) */ } #else rc = vsnprintf (str, size, fmt, va); #endif va_end (va); return rc; } Of course it is also possible to get rid of...

Oh, I forgot to mention that besides setting AR, RANLIB and the stack probing fix, you also need a very up to date binutils. 2.25 was out in december. Even with that , if you linker's default is not what you are compiling for (i.e. a multiarch toolchain), you need to set GNUTARGET also, i.e. -m32/-m64 is not enough. Some fix to autodetect non-default targets went in after christmas before the
