NettetSince the __uint128_t type is a GCC extension, the proper thing to do is probably to check for some known-good version of GCC. See this page for information about the macros … In particular, if __int128 and unsigned __int128 were extended integer types, then gcc would be required to define intmax_t and uintmax_t as those types (or as some types at least 128 bits wide). It does not do so; instead, intmax_t and uintmax_t are only 64 bits. This is, in my opinion, unfortunate, but I don't believe it makes gcc non-conforming.
