This appears to be missing a bunch of macros internally defined by 
MIPSpro and not listed by the "CC -v" verbose output.  One of these 
macros is _LIBC_IN_NAMESPACE_STD_ which is causing the error in the 
cmath header.  I've updated gccxml's knowledge of how to find 
preprocessor symbols to detect these internally defined macros:

/cvsroot/GCC_XML/gccxml/GCC_XML/Support/MIPSpro/find_flags,v  <-- 
find_flags
new revision: 1.5; previous revision: 1.4

The change should solve the problem (of course there may be others).
