:Gee, that sounds familiar!  Plexus Sys3 3.31 cc has either the same or a

:and the "if" and "while" statements not only expect this type, but they also

:Does Plexus System V cc have that bug fixed, or should we contemplate
:something else for ncoast?

Perl works fine on Plexus System V, as we run it here.  I guess they
fixed that problem.  Actually, Plexus didnt write their own compiler,
but used the portable C compiler from AT&T.  The Sys3 and Sys5 compilers
are very different.  Also, green hills C does fine on Perl.
