Andrew is correct, math.h is not provided by GCC.
TR 24732 is not supported by GLIBC and probably won't be until it is
incorporated into a C standard. Meanwhile it is in a branch of the EGLIBC
project, but I understand that it is difficult to build so I'm not sure how you
could use it for testing.
To avoid "warning: ISO C does not support decimal floating point" compile with
-std=gnu99.
