Fail to build octave with GCC 4.1.2

[RickG]

The same thing happened to me in Ubuntu 9.04.  The problem is that the
library
libg2c, which is needed by GNU Fortran 77 code, was not loaded or linked.

I loaded it with the Synaptic Package Manager, where the thing to load was
called libg2c0.   this then installed a link called  libg2c.so.0 to the
loaded
library in /usr/lib

Then the problem of getting it to link.  I got it to work, but somebody
should
install an option in the configure process for GNU Fortran that deals with
this.

what I did was edit the Makeconf.in file where it had

FLIBS = @FLIBS@

to be

FLIBS = /usr/lib/libg2c.so.0 @FLIBS@

it would have been nice if     -lg2c    would have worked, but it didn't.
There is probably a better way to do this.   then    make clean     and 
./configure  and   make again.

After this fix, it got past building libcruft,  then bombed on trying to
make (or remake) some documentation.
I don't know if that was caused by the    make clean     .

Anyway, after loading a few more things to deal with that, everything
completed and it passed   make test
(as much as it is supposed to, given the current state of things).
