Hello All,
This bug allowed direct references by name to PDT instances. It took
me a long time to have the necessary light bulb moment: The names of
PDT instances never have to go through the scanner and so are not
subject to the ministrations of gfc_wide_tolower. Therefore, rendering
all the letters of the PDT prefix in upper case prevents pdt_types
from being directly referenced in code.
I took the opportunity to define PDT_TEMPLATE and PDT_TEMPLATE_LEN in
gfortran.h.
The chunk in resolve.cc is a funny one. I had previously encountered
the test for assumed LEN parameters in typebound procedure dummies
(pdt_37.f03) failing due to apparently unrelated changes in the
frontend. It seems that it is the order of appearance of pdt_templates
and pdt_types that mattered. The problem is fixed by testing for both,
as is necessary for this patch to pass regression testing.
Regtests OK with FC43/x86_64. OK for mainline? I will be offline for a
few weeks from Monday evening and so I will push the patch then if it
hasn't been reviewed. In the words of Hitchhikers Guide to the Galaxy,
it is "mostly harmless".

OK for mainline Paul, thanks.
