Sorry, I guess I lost track of the snapshots you were packaging.

I think __math.h is the file.  Here is small diff (cut & paste) from 
2.0.5 to 2.0.7:

*** __math.h205 Sun Mar  8 00:00:29 1998

It seems __NO_MATH_INLINES must be defined.  2.0.5 tests for __GNUG__.
2.0.7 does not, but only checks for __GNUC_MINOR__ <= 7. This would
explain why 2.8.0 also fails.
