 swprintf has different signatures in mingw32, where it does not include
 the
 buffer size, and in mingw-w64, where it does. That of course breaks the
 code
 as mingw-w64 treats the pointer to the format string as a size_t. Bummer:


 C:/.../inplace/mingw/i686-w64-mingw32/include/swprintf.inl:30:5: note:
 expected 'size_t' but argument is of type 'short unsigned int *'
  int swprintf (wchar_t *__stream, size_t __count, const wchar_t *__format,
 ...)
      ^

 rts\Linker.c:1986:12:
      warning: passing argument 2 of 'swprintf' makes integer from pointer
 without a cast [enabled by default]
                 swprintf(buf, L"lib%s.DLL", dll_name);

 I have a fix pending to use snwprintf instead.
