Thanks for the advice - I tried running the portion of the configure script
that checks for g77 appending an underscore, and it seems that it does
append the underscore:

linus% more conftest.f

      subroutine xxyyzz ()
      return
      end

linus% gcc -c conftest.f
linus% more conftest.o
ELFCC: (GNU) 2.8.1.symtab.strtab.shstrtab.text.data.bss.comment4!HH,
HZ5q!conftest.fgcc2_compiled.*ABS*xxyyzz_

I tried performing the same test on getsd.f in the libcruft/ranlib directory,
and the object file contains the line (among other things):

ELS[rgetsd.fgcc2_compiled.__g77_cilist_0.0*ABS*getsd_qrgnin_s_wsledo_lioe_wslexstopx_getcgn_globe_

It appears that g77 is appending the underscore. Is there any way to tell if
these functions are being properly built into libcruft.a and libcruft.so?
I tried building everything without the underscore, and had the same error
output, namely the compiler could not find the libcruft functions like getsd,
setsd, etc. Any further suggestions would be appreciated! I am interested
in evaluating octave for my analysis needs, as much of my Matlab code is
fairly generic.
