To quote notebook/problems:
---
.SH
Values of Logical Operators
.PP
There seem to
be compilers, e.g. the Ultrix one on DEC's new RISC workstations,
that go into convulsions when they see something like
.DS
*p++ = isascii(c) && isalnum(c);
.DE
because they don't know how to generate a numeric value for `&&',
or because they don't know how to turn that value into a `char'.
One or two places in C News use constructs like this.
If you run into this, you might
want to try replacing the
right-hand side
with something like ``(...)\ ?\ 1\ :\ 0'' to get the
troublesome operator back into a conditional context.

The current DEC MIPS compiler is broken.  Be sure to file an SPR so that
DEC fixes this.
