Is PG_ACC_BUGS still necessary?

[pramodk]

CoreNEURON has following macros :

→ grep -r ACC_BUG coreneuron/*
coreneuron/mech/modfile/hh.cpp:#if defined(PG_ACC_BUGS)
coreneuron/nrnoc/eion.cpp:#if defined(PG_ACC_BUGS)
coreneuron/nrnoc/register_mech.cpp:#if defined(PG_ACC_BUGS)
coreneuron/nrnoc/nrnoc_ml.h:#if PG_ACC_BUGS

Todo for this ticket :

• Check when PG_ACC_BUGS was introduced and what was the purpose
• If it was due to some old version, check if the issue doesnt appear with current 18.4 PGI compiler
• If so, remove related code from CoreNEURON as well as MOD2C
