Large Unit number g77

[Fabian Braennstroem]

Hello everybody,

I just start programming in Fortran. From my professor I got  a
fortran-program which he used on a sgi. Now I try to get the program
running under linux (debian/woody (g77-3.0)).

I have no big problem compiling the sources, but when I start executing
it, I get an error like: 'illegal unit number'.
I think it is because of a couple large unit numbers. So I tried to fix
the 'gcc/libf2c/libI77/fio.h', but I can't find it!
Does anybody have an idea where to look?

Thanks and Greetings!
Fabian

P.S. What can I use for 'etime' and 'dtime' under Linux?
