OpenMP on gcc

[Ferad Zyulkyarov]

As I know, OpenMP is being implemented since version 4.2+ But these
gcc versions does not have official release. Based on my experience, I
compiled few simple OpenMP programs in gcc and I was satisfied.

> 1) Starting from which version does GCC support OpenMP ?

As I know 4.2

Based on the pragma specification unknown pragmas are ignored. But you
have to deal with the omp_* stuff (i.e. omp_set_lock function)
