my concern with style A as it is currently deployed is that the
configuration settings are down in pkgsrc/mk/compilers/gfortran.mk
where it is not that easy to find.  e.g. compared to the C/C++
compiler settings which I think come from the bootstrap script's
"--compiler" flag and are placed in $prefix/etc/mk.conf...

i had not thought about flang being an option, so that's also a
good point that you've made.

yeah, i don't know either, but it's clear the gcc12 setting is
starting to bit rot...
