Pedantically !$omp must be followed by space to be valid, but seems
there are several OpenMP Fortran sources in the wild which use tabs.
The following patch accepts them (gfc_gobble_whitespace will take
care of pedantic warnings about tabs).

Old version: A warning is printed unconditionally and "!OMP$\t" lines are regarded as comment.

This patch: "!OMP$\t" is regarded as "!OMP$ " and no warning is ever printed.

Note: The warning does not seem to work for

!OMP$\tparallel

it only becomes active for

!OMP$\t\tparallel

I think one can change the behaviour to allow "!OMP$\t", but either by default or when using -pedantic a warning should be printed.
