AFAIK, GCC support OpenMP 4.0. On p. 26 of OpenMP 4.0 Standard, one
finds
Restrictions
The following restriction applies to all OpenMP directives:
· OpenMP directives may not appear in PURE or ELEMENTAL procedures.
so you get the above error message. I'll note that OpenMP 4.5 Standard

Restrictions
The following restriction applies to all OpenMP directives:
Restrictions
· OpenMP directives, except SIMD and declare target directives,
may not appear in pure
procedures.
I'll further note that the GCC wiki page for OpenMP sugeests that
no one is actively working on $.5 support.
