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.
