gcc-14/changes.html + projects/gomp/: OpenMP + OpenACC update

Update OpenMP for two meanwhile implemented features (lvalue-expr in map,
indirect now also in Fortran).
Update OpenACC for one new feature (Fortran interface to exisiting
C/C++ routines).

I would omit the comma after "C and C++".

+      <code>acc_memcpy_to_device_async</code>,
+      <code>acc_memcyp_from_device</code> and
+      <code>acc_memcyp_from_device_async</code>.

Oxford comma (i.e., comma before "and")?

Looks good to me (with or without my recommendations).

Thanks,
Gerald

Thanks -- but you have to improve your copy'n'paste skills.  ;-P
