too bad (the "stop for now").

This is exactly the typical result of the next item :
In my experience, whenever is.finite(), finite() 1/0, 0/0 etc weren't ok
(and as Peter emphasized, they are *not at all* as long as you get
 "INF" and "NaNQ" instead of "Inf" and "NaN")
then the graphics show the above symptome.

The way that I found that -D_XOPEN_SOURCE_EXTENDED
will save me, was by looking into /usr/include/math.h

It seems that you (and Thomas Vogels !) have a different one, than, even
though Thomas said that he had AIX 4.2 as well?
This is what I have :

    $ uname -a
    AIX percol 2 4 000333104600

    $ ls -l /usr/include/math.h
    -r--r--r-- 1 bin bin 14620 Oct 14 1996 /usr/include/math.h

What versions of AIX 4.2 are around?

KH> * IEEE fp stuff is strange (will look into this).
KH> * I still need f77 for linking. Using ld with the suggested flags gives
KH> a binary with `exec format error'. The problem seems to be with an
KH> unreferenced __start.
KH> * The basic add-ons seem to work, though.

KH> Status HPUX:

KH> * I can compile the main binary with c89/f77/make.
KH> * Compilation fails in eda (syntax error in etc/Makeconf). The problem
KH> disappears when the SHLIB target is commented ... but then building

                                       sure about that ??

KH> * QUESTION: what about src/unix/hpdlfcn.c?
