I don't think that's it. The pattern is "1.[0-9]+" and the plus regexp
should match one or more digits. So it should match "1.12".
I notice that the solaris_math_* fix hacks all seems to have a bypass clause
on "GNUC". Sometimes the solaris headers try to be gcc-aware. Is there a
GNUC appearing in solaris11's /usr/include/iso/math_c99.h header? And that
begs the question, why do these fix hacks have this GNUC bypass in the first
place?

Thanks but I meant: of the many if-aborts, which is triggered when running
under gdb? That will tell us which builtin is failing. (May be they all
are.) I don't know what the header looks like to know what if anything
should be changed by fixincludes.
