Sounds a good aproach for solving the code generation problem.  
Thus you don't need an omp aware compiler to work on the lib.
You can transform (rewrite 'by hand') code containing omp directives
into a code with calls to the libgomp.  I think that the compiler 
will insert these calls sooner or later using a similar algorithm.  

I suggest you write these examples in a canonical form:
- code with pragmas: file_omp.c
- code with calls to libgomp: file_libgomp.c
or something similar. 
We could reuse them as a test suite for code generation once we'll 
have a compiler that generates code.

We'll insert calls to libgomp.  You could write 'by hand' code that the 
compiler will generate in a few months. 

For the moment I work on the g++ parser and have a little idea of how to hack 
the lexer in order to be able to generate tokens as suggested by Zack and 
David: 

#pragma foo bar baz

into

__builtin_pragma foo bar baz;

Once I have something that works I'll send a patch for collecting more 
comments from GCC people.
