No.

I can't begin to describe how messed up this area is.  I could start
with K&R C and AT&T Unix (which had excuses), ISO C and POSIX (which
didn't) and carry on from there.  The one thing that I can say is
that the compiler (i.e. gcc, sensu stricto) has nothing to do with
the matter.

This is entirely a library and operating system issue and, by the
sound of it, you are knackered.  You can try creating such a file
using the underlying POSIX calls and see if that works.  You may
need to specify O_LARGEFILE in the open call.
