[Cleanup] Remove unsupported pre-processor directives
There are a lot of unsupported directives for cpp
and fpp
:
-
pgiFortran
: as mentionend in #121 (closed), we will drop support until the new flang compiler is available -
pgiFortran154
: same as withpgiFortran
-
GFORTRAN41
: since we only supportgcc >= 7.3
we can drop this one -
ABSOFT
: we only supportGNU
,INTEL
andNAG
-
MPR_STANDALONE
: MPR will be provided as a dependency starting withmHM v6.0
(@ottor should we keep it for now?)
I would like to remove these directives, so the code-base gets cleaner.
