No.  AFAICS so far C99 functions have been implemented in
intrinsics/c99_functions.c for the benefit of platforms that aren't
C99.  Has this policy changed recently?  

I don't think it's a good idea for libgfortran to contain references to
nonexistant functions (or for gfortran to emit references to C99
functions on non-C99 platforms, if that's the case).  At least that's
not what any other GCC language frontend does.
