I'll use "When using GCC," :)
It is, but the GNU project is a large organisation, and has nothing to
say about non-standard types defined by GCC. Just because GCC is part
of a larger proejct, doesn't mean the entire project defines
something.
Ok.

That's what I had first: "Conforming to: GCC extension"
Then I thought that I could include the version information,
so I changed it to that.
Maybe "GCC extension (since GCC 4.6.0)" would be better?
I don't think that information belongs in the Conforming To section at
all. The version that added the type is nothing to do with
conformance, because it's an extension and there is nothing to conform
to.
Look at 'man clock_gettime' for comparison. It has a VERSIONS section
and some individual constants are annotated with "(since Linux
2.6.12)". That seems more appropriate for annotating individual types
within this man page which are not universally available.
Thank you!
Updated:
[[
__int128
A signed integer type of a fixed width of exactly 128 bits.
When using GCC, it is supported only for targets which have an
integer mode wide enough to hold 128 bits.
Versions: GCC 4.6.0 and later.
Conforming to: GCC extension.
Notes: This type is available without including any header.
Bugs: It is not possible to express an integer constant of type
__int128 in implementations where long long is less than 128
bits wide.
See also the intmax_t, intN_t and unsigned __int128 types in
this page.

Just one more thing:
Would you say "GCC extension" or "GNU extension"?
Thanks,
Alex
