I still hope we'll get this (that is, <https://gcc.gnu.org/PR70598>)
fixed in time for the GCC 6.1 release.  I'll keep you posted.

Sorry for being unclear.  My idea/question has been whether you're
interested in helping by translating the documentation as well as the
libgomp.oacc-c-c++-common/context-*.c test cases from C to Fortran (using
the OpenACC host_data construct instead of the acc_* functions).  If yes,
then that's great, if not, then one of us will do it at some point.
