Sorry for the incomplete post. Here is the complete story:

I tried looking into what might be wrong and have the following thoughts:

In gcc/cp/parser.c, line 17661, there is the following assertion

assert(id >= PRAGMA_FIRST_EXTERNAL);

This is infact the assertion which is failing. On looking up the enum for the
OMP pragmas in gcc/c-pragma.h, I find that PRAGMA_FIRST_EXTERNAL is defined
after all the OMP pragmas and hence this assertion will always fail. I was
under the impression that the C++ front-end was also ready to be used. Is this
something which has been done intentionally?

I have never looked into gcc sources before, so if my question or comments seem
stupid, please take it with a pinch of salt.

Anju

This was a big misunderstanding. I thought all the front-ends for openmp had
been integrated into trunk. it seems like only the C one has been integrated. 
I downloaded the right branch as mentioned on the web-site.
