little things ...

    I have been doing some alpha testing on glibc-1.07.4[an alpha release :-)]
so I thought I'd see what I ran into building Octave-1.0. I am using gcc-2.58 
and libg++-2.5.3 on a SPARC10 running OS4.1.3. 

    The first "surprise" was that the configuration process opted to use f2c 
rather than the unbundled SUN fortran, version 1.4, in stalled on the system. 
Is that normal?

    The second "surpise" was a multuple definition of "_z_abs"; one from
libf2c.a and the other from libc.a. I got around this by yanking z_abs.o from
libf2c.a. With this change octave was able to link.

    Next I ran the tests in the test directory:

address@hidden make

Target is sparc-sun-sunos4.1.3
Host   is sparc-sun-sunos4.1.3

                === octave Summary ===

I believe that the infnan test requires an "infinity" function. Sun's math
library has one. Glibc does not. Is this an IEEE requirement? If so I will
tell the maintainers of glibc to add it.

    I don't know what npsol is? There was a reference to it in the README.NLP
as something you need a license from Stanford in order to use it. So that would
certainly explain the othe two failures. So..., it looks like glibc may be 
OK for this application.

    I've started looking at some of the examples shown in the info doc. Is
plot (x,t) supposed to work? The parser complains that it does recognize
"plot". I have gnuplot installed. The parser recognizes "gplot x".

    What about dynamical linking? The config files seem to indicate that
