Hi again,
just little more details:
I'm currently blocked by the following issue. If I try to compile,
with -std=gnu++98 (the default for C++) and -pedantic-errors:
template
struct limits;
template<>
struct limits<__int128> { };
template<>
struct limits { };
I get:
a.cc:8:26: error: ISO C+

I'm about to do) better doing everything in terms of __int128 and
unsigned __int128.

Indeed!
The documentation is not clear on whether __int128 and __float128 may
be the same types as say long long and long double, or they are
different types even if they have the same size (the doc was written
for C, where it doesn't matter as much).

Hello,
bugzilla seems to be down, so let me write it here:
the testsuite uses #ifdef __SIZEOF_INT128__ to test for the availability
of a 128 bit integer type. I haven't seen a similar define for float128,
Hi,
