By the way, if people interested in types __int128 and __uint128 are
willing to have a look to libstdc++/40856, I attached there a patch
implementing numeric_limits<__int128> and numeric_limits<__uint128>
which seems almost ready to go in for 4.6.0... In particular, I'm I
right to assume that the facilities are available for:
#if ((defined(__LP64__) && !defined(__hppa__)) || defined(_WIN64))
?? Other comments?
Thanks,
