intmax_t vs (extended) integer types

[Paolo Carlini]

Hi everyone,

I'm analyzing the proposed resolution of this issue:

   
http://wiki.dinkumware.com/twiki/pub/Wg21batavia/LibraryWorkingGroup/incomplete_spec_of_cinttypes.html

which tries to resolve a conflict with the abs and div overloads for
long long, by specifying that <cinttypes> adds overloads for intmax_t
only when the latter is an actual extended integer type, thus does not
boil down to any standard integer type.

I'm looking for help in figuring out whether this situation can really
happen with GCC on the supported targets, in particular in relationship
to the work on inttypes.h. Certainly doesn't happen on Linux, where it's
just long long, as far as I can see...

Thanks in advance,
Paolo.
