AFAIK there is just one function call to libg2c/f2c [1], which is in:

.libs/fdate.o: In function `fdate_':
/usr/local/src/Packages/mopac7/mopac7-1.13/fortran/fdate.c:27: undefined
reference to `s_copy'
collect2: ld returned 1 exit status

If we/you could replace s_copy() there, libg2c/f2c would become
obsolete. No other functions are used and in Debian we already compiled


Hello,
this sounds like a good plan. The s_copy implementation is rather small in libf2c and perhaps we can copy it into fortran/s_copy.c ; then all we need is a fortran/f2c.h which contains enough stuff to make everything work. I will try this but it can take a few days...

Regards,
Tommi
