Not with pcc-current.

Apparently you fixed both at once. I can reproduce neither the optimi-
sation bug nor the bool bug any longer. Great! pcc becomes usable.

Find attached two diffs:
• for the manpage: even if SCO Unix ® uses GNU groff, not every other
  unixoid operating system does. AT&T nroff does not grok all GNU
  extensions to the troff languge – the attached diff makes the man-
  page source portable between both *roff processors (and possibly,
  ditroff and Plan 9's nroff)
• for the compiler driver: quick hack until switching to getopt:
  recognise -O0 and turn off optimisation (untested, but I would
  *VERY* much like this functionality to go in; I don't know what
  the standards say about supporting -O0 but I'm pretty sure that
  many people understand me being annoyed when -O0 == -O1 and the
  optimiser has bugs – which it had until today).

Thanks!
