Ugh -- I'm not up to date on CVS and my internet connectivity is flaky 
(new cable modem on Wednesday) so I hope somebody else could do so 
instead.  This has to be done on both the 3.4 branch and mainline of course.

When you revert my change, please add a comment to the math_exception 
hack regarding the problem:

/* This should be bypassed on __cplusplus, but some supposedly C++
 * C++ aware headers, such as Solaris 8 and 9, don't wrap their struct
 * exception either.  So currently we bypass only for glibc, based on
 * a comment in the fixed glibc header.  Ick. */
