Leading underscore in reference label

[Dale Scheetz <dwarf@polaris.net>]

I've tracked down the problem I have been having building octave. The 
source code for the package is in Fortran. The unsatisfied externals are 
all f2c library calls. In the library causing the error the reference is 
to do_fio, but in the f2c library the label is _do_fio, hense 
unsatisfied. I remember Borland C++ going through a phase where the 
leading underscore went from being automatic to requiring a compiler 
option be set. So, I spent a fruitless half hour searching through the 
info tree on gcc without seeing anything on the topic. Either f2c needs 
to do this or there is an option for gcc. Since this package built ok for 
the a.out release something has changed in the newer versions of either 
gcc or f2c.
Can anyone improve my knowledge on this? 

TIA,

Dwarf
