The report omits the essential information, which is the configuration.
This only affects __LDBL_COMPAT configurations such as powerpc.

I committed a fix on the trunk (commit 36c8acb) though I did not test it on
an affected configuration.
I don't think the bug actually appeared for this case on the trunk
beforehand, because _GNU_SOURCE gets __USE_XOPEN2K8. But probably there
was some other bug in 2.13 like _POSIX_C_SOURCE defaulting wrongly for
_GNU_SOURCE.

Rebuilding gcc with 'with-long-double-128' also fixes this issue... that makes
sense though, since these DEFINES are sort of related to that bit?
Going to retest with just the header fix now.

Yes, that's expected. The problematic code is for machines that can have a new
long double type, but previously didn't.
