<iso/math_c99.h> has indeed been made GCC-aware in Solaris 11, as Joseph
explained.

In c99-math-double-1.c, the first C99_MATH_TESTS invocation abort()s.
Single-stepping in gdb (which couldn't display the macro, even if compiled
with -g3 ;-) revealed that this clause

  if (fetestexcept (FE_ALL_EXCEPT) != 0)                \
    abort();                                            \

fails.  fetestexcept() returned 0x10, i.e. FE_INVALID.

Hope this helps.

        Rainer
