[Bug preprocessor/27746] ICE on openmp code when using _Pragma from macro

[jakub at gcc dot gnu dot org]

------- Comment #10 from jakub at gcc dot gnu dot org  2006-05-25 12:29 -------
 #define parallel _Pragma("omp parallel")
 int
 main()
 {
 #pragma omp parallel
 {}
 }

is ICE on invalid code, OpenMP 2.5 says in 2.1 Directive Format:
Preprocessing tokens following the #pragma omp are subject to macro
replacement.
And, #pragma omp _Pragma ("omp parallel")
is of course not valid.
