I have just uploaded Math::Int128 to CPAN

Just tried building it using the mingw64 compiler, and it failed spectacularly. I speculate that this is a shortcoming of the compiler ... though it does have the 16 byte __int128 data type. However, the __int128 data type appears to be a signed value only.
The "unsigned __int128" is, afaict, an unknown type and, I suspect, the cause of the errors reproduced below.

Trying to determine sizeof(unsigned __int128) in a C program produces the compile-time error:
expected ')' before '__int128'

Salva, let me know if there's any point in following this further with that compiler, and I'll certainly try to work through it. Here's what I get when running dmake (x64 build of perl-5.12.0):

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
