When an specification statement in a BLOCK construct has a
PARAMETER attribute, gfortran currently discards the entity.
This patch marks PARAMETER entity if in a BLOCK.  I'm not
complete convince that this is the right fix, but it does
allow the testcase to compile and run.  Built and tested
on x86_64-*-freebsd.  OK to commit (if not no one has a
better patch)?
