in thread Module for 128-bit integer math?

I get:
C:\>x86_64-w64-mingw32-gcc --version x86_64-w64-mingw32-gcc (GCC) 4.6.0 20100414 (experimental) Copyright (C) 2010 Free Software Foundation, Inc. This is free software; see the source for copying conditions. There i +s NO warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PUR +POSE. C:\>
Update: But, in addition to the version number, there's also the consideration of what features have been ported to MinGW.

Cheers,
Rob

    Your compiler is almost one year old. Support for unsigned __int128 types was probably not yet implemented.

      A post to the mingw64 mailing list suggested that I create the __uint128 type myself (in the compiler's _mingw.h) with:
      typedef unsigned int __uint128 __attribute__ ((__mode__ (TI)));
      and that works fine.
      Then, in Int128.xs, it was just a matter of changing:
      typedef unsigned __int128 uint128_t; to typedef __uint128 uint128_t;
      BrowserUk (or anyone else, of course), if you want a ppm package of that module that will work with the 64-bit builds of ActivePerl (both perl-5.10 and perl-5.12):
      ppm install http://www.sisyphusion.tk/ppm/Math-Int128.ppd

        Thanks syphilis. That works perfectly.

        And especially thanks to salva.

        I still intend to pursue an MSVC/SSE* solution to this, but this gives me a reference point.
