OK, I gave up trying to get rid of those signed char warnings (looks like Mike's
done a search-and-replace to convert ALL char's to signed char's !) with
4.0 PL 67 and set out to compile it, warnings and all.

Mike's global replace seems to have hit the prototyping (is this needed
anyway ? Don't the system header files do this ?) in uxdsp.c and nuxdsp.c.
Basically, the char *'s have become signed char *'s, which conflicts with the
prototypes defined in the system header files (for HP-UX systems in ANSI mode
anyway). Here's the context diffs (which include a #else fix for search.c,
because ANSI cpp doesn't normally support #else if defined, but does support
#elif defined):

I hope this all helps - it gets 4.0 PL 67 compiled under HP-UX 9.01 on an
HP 9000/710 [with about 30 screens of warnings :-( ].
