The idea was to only include it when needed for clang. But of course it's
already included by  and so that check is pointless.

I think we might want to use the built-in for isxdigit as well, because the
built-in ignores the locale which is what we want here. Or we should just
replace toupper and isxdigit with locale-independent equivalents.

It sounds like the most reasonable fix as this is how toupper is being
called.

I think the real problem is that include/c_global/cctype is missing
the NAMESPACE_VERSION macros.

All declarations of std::isxdigit etc should be in the same namespace,
precisely so we don't need to do this.


Didn't you want to fix it this way then ?

To be honest I was a little bit lost by this code:

#if !__has_builtin(__builtin_toupper)
# include 
#endif

Looks like cctype is included only for toupper, why not for isxdigit ?

I think the real problem is that include/c_global/cctype is missing
the NAMESPACE_VERSION macros.

All declarations of std::isxdigit etc should be in the same namespace,
precisely so we don't need to do this.
