These are reserved functions (7.26.1), not functions defined by C99.  So 
they shouldn't be DEF_C99_BUILTIN; DEF_EXT_C99RES_BUILTIN, similar to 
DEF_C99_C90RES_BUILTIN for names reserved in C90 and added in C99, would 
be more appropriate.

I suppose you're only adding clog10* not all 27 functions (cerf, cerfc, 
cexp2, cexpm1, clog10, clog1p, clog2, clgamma, ctgamma and float and long 
double versions) mentioned in 7.26.1 because glibc only has the clog10 
functions and you don't know of any systems which have implementations of 
the others which would benefit from the built-in functions?
