See Dave Malcolm's patch, please integrate it into your patchset.

I'd write:
"This manual documents the GNU implementation of the OpenMP API
for multi-platform shared-memory parallel programming in C/C++ and Fortran
and OpenACC and OpenMP API for offloading of code to accelerator devices
from the same languages."
or so.

If the env var name is adjusted to GACC_NOTIFY, GOACC_NOTIFY or even
GOMP_ACC_NOTIFY (as the library is libgomp), please don't forget to change
this spot too.

Otherwise LGTM.
