Hi!
I ran into this while working on something else, and it turned into a
prerequisite. Committed to trunk in r266684:
commit ba688147af7632d7e1c420c98f2d301f7b9e427c
Author: tschwinge <tschwinge@138bc75d-0d04-0410-961f-82ee72b054a4>

Support multiple OpenACC wait clauses
Support for this is not explicitly called for in OpenACC 2.6, but given that
GCC internally decomposes "wait (1, 2)" into "wait (1) wait (2)" (similar
for
other clauses, too), it's reasonable to also support that syntax in the
front
ends -- which happens to already be the case for C, C++, and easy enough to
do
for Fortran.
gcc/fortran/
* openmp.c (gfc_match_omp_clauses): Support multiple OpenACC wait
clauses.
gcc/testsuite/
* c-c++-common/goacc/asyncwait-5.c: New file.
* gfortran.dg/goacc/asyncwait-5.f: Likewise.
