Really strange...
I did the same, and indeed there's nothing for parsing C/C++ OMP.
Maybe they changed the C/C++ front-ends just before releasing their 
compiler into GPL?  That is just a supposition, I have to look 
closer at the diffs below...

I found in version.c the right version of their checkout:
-const char *const version_string = "2.96 20000530 (experimental)";
+const char *const version_string = "sgicc-1.0 {2.96 20000530 (experimental)}";

I checked some versions and just piped the result of a diff into wc
and minimized the size: you get a minima at
- for C:
cvs up -d -D "2000-05-30 10:00"
- for C++:
cvs up -d -D "2000-06-05 23:00"

I diffed the gnu directory for C and C++ front-ends.
