octave fails to detect gcc 3.1's f77 as a compatible compiler: checking whether g77 is the GNU Fortran compiler... yes checking g77/f2c compatibility... no checking for f2c... no configure: warning: in order to build octave, you must have a compatible configure: warning: Fortran compiler or f2c installed and in your path. This might be caused by a g77 bug; please verify and reassign if necessary.
gcc-g77-3.1-0.7 gcc bug - it can't even compile the FORTRAN version of "hello, world": [teg@oslo teg]$ g77 -o hello hello.f /usr/bin/ld: cannot find -lfrtbegin collect2: ld returned 1 exit status [teg@oslo teg]
Created attachment 37522 [details] "hello, world" - the FORTRAN way
Fixed in my gcc31.spec copy, will be in gcc-g77-3.1-0.8.
