Re: [patches] Re: Bug#582698: libc6-dev: INTMAX_MAX definition yields build failure in 32-bit C90 mode though intmax_t is supported

The natural approach to fix this would seem to be to use __extension__ in 
the definitions of __INT64_C and __UINT64_C and the associated INT64_C 
etc. macros, when those use long long suffixes.  That should avoid the 
failures for strict C90 when using a compiler recent enough to have the 
(partial) fix for GCC PR 7263.  I see no reason this should be 
unacceptable for FSF glibc (though one can never entirely predict how the 
FSF glibc maintainers will react to a given patch).
