A lot of this looks like problems with configure using the wrong cpp
to do C preprocessor tests. In particular the syntax errors in the
include/catalog files suggest that configure's conclusion that you
have pre-ANSI preprocessing:
> checking for preprocessor stringizing operator... no
is wrong. I see
> checking how to run the C preprocessor... /lib/cpp
and I wonder whether /lib/cpp is actually equivalent to /usr/bin/cc's
preprocessing. Does /usr/bin/cc accept a -E switch? If so, why didn't
configure use that? (Do you maybe have CPP=/lib/cpp in your
environment?)

Also, where did configure come by all these switches for cc:

> checking whether the C compiler (/usr/bin/cc -O3 -I/usr/freeware/include -L/usr/freeware/lib32 -L/usr/lib32) works... yes

Bottom line is that I suspect configure is being misled by some of
your environment settings. But another possibility is that
src/makefiles/Makefile.irix5 is doing something inappropriate.
In particular I wonder why it has
override CPPFLAGS += -U_NO_XOPEN4
Is this (still) appropriate for IRIX? If so, perhaps it needs to be
done in src/template/irix5 instead (so that configure will see it)?
