Could somebody with a SunOS 4.1.3 (or 4.1.x, I guess) system look
into this?

In particular, I wonder if this is a case of the wrong c_abs, z_abs,
or f__cabs being linked in (e.g. from a non-libf2c/libg2c library)?

We had that problem come up years ago during g77 alpha-testing, IIRC
on this same machine.  I think Kate Hedstrom ran into that, and it
was basically due to not linking the libraries in the right order.
(And, now that I've changed some naming and placement of the libf2c
library...maybe the problem has resurfaced?)

Not that I'm aware of.

We should probably just add -lm all the time.  I'd be amazed if systems
without libm would even get far enough to try running the testsuite :-)

The g77 driver does this automatically.  By "this" I mean adds -lg2c -lm.
In fact, I think if you specify -lg2c, it adds -lm after it; and if
you specify -lm, it adds -lg2c before it.  Haven't tested that for
awhile.  (But most of this is only since snapshot 19980615 or so;
before that, adding -lg2c -lm was done rather "mechanically".)

Please don't do this.  BeOS should be able to run the testsuite just
fine, once I install an updated dejagnu.

I suspect that's not testing the right thing, though.  You should use
the `g77' driver, which is analagous to the `g++' one; the `-v' switch
can be helpful.  What's the output from the test in the testsuite
g77.log?

 AO> Does anyone know how we can add `-lm' to the link command of this test

The relevant line from `g77 -v cabs.f' on a non-egcs installation I
have available on sunos4 is this (which works):

 /usr/local/lib/gcc-lib/sparc-sun-sunos4.1.3/2.7.2.3.f.1/ld -e start -dc -dp /lib/crt0.o -L/usr/local/lib/gcc-lib/sparc-sun-sunos4.1.3/2.7.2.3.f.1 -L/usr/local/lib /tmp/cca196901.o -lf2c -lm -lgcc -lc -lgcc

(You should see -lg2c now, not -lf2c.)  If it's really a problem with
-lm, the question is whether the library list needs to be permuted or
added to somehow.  Thanks for any light you can shed.

The problem seems to have something to do with linking libm before
libg2c.  Since the testsuite links with -lm but not with -lg2c, ld is
called like this:

Here is a patch that should fix this problem.  I'm putting it into
g77 0.5.24 as well.  Dave Love, once this patch is confirmed as
working by Alexandre or someone else on SunOS4, could you please
install it?

The news.texi that I've written for 0.5.24 (and will later
submit patches to clean up egcs-g77's news.texi shortly before
final testing) is:

@item
The @code{g77} driver now ensures that @samp{-lg2c}
is specified in the link phase prior to any
occurrence of @samp{-lm}.
This prevents accidentally linking to a routine
in the SunOS4 @samp{-lm} library
when the generated code wants to link to the one
in @code{libf2c} (@code{libg2c}).

I took the liberty of installing this patch now instead of waiting.
I'd like it to be in the next snapshot (which will spin tonight) for
testing purposes.

If this causes problems, blame at me, not David :-)
