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
2) Will old versions of GCC just ignore OpenMP pragmas, or these
will cause errors ?
Based on the pragma specification unknown pragmas are ignored. But you
have to deal with the omp_* stuff (i.e. omp_set_lock function)
