Thank you, Orion!

That will also solve the problem,
and is certainly neater than stripping off the "-pthread" flag
with a fake compiler script.

I didn't know about "-noswitcherror", so many switches there are,
not all of them very clear, and the number is growing ...

The only problem I can think of would be if you misspell another switch,
one that you really want to use.
Man pgf90 says it will accept the misspell/mistake
with a warning message.
So, to be safe with "-noswitcherror",
one has to grep the make log for PGI warning messages, I suppose,
which is no big deal anyway.
