I'm trying to classify Transputer C compilers according to whether they
handle concurrency by language extensions or by a library of special functions.
If you know about any particular C compiler, would you care to let me know
whether it
  (a) has a special type for channels?
  (b) does input by
      (1) evaluating the name of the channel as if it were a variable
      (2) by a function call
      (3) some other way
  (c) does output by
      (1) assigning to the name of the channel as if it were a variable
      (2) by a function call
      (3) some other way
  (d) has special constructs for PAR and ALT, or uses special functions?

Also I would like to reduce my list of compilers by eliminating any which
are merely relabellings of others.  I have got Pentasoft, Renishaw, "Penguin"
from Cornell, 3L, Parsec, Norcroft, Logical Systems and Definicon on the list.
Are there any duplicates here?  Are there any missing?

I think I've read seen all the relevant items in this news group over the last
six months or so - thanks to those who have contributed it - apologies if I've
missed your item - if you have already answered my questions, just give me the
reference and I'll find it in the back numbers.

    Many thanks,
