>Description:
Fortran programs don't link after the gcc-3.1 due to a missing
libfrtbegin.a. libF77/main.o was split out into libfrtbegin in
gcc-3.1 and a dependence was built into g77 (via g77spec.c) to
unconditionally link libfrtbegin into all Fortran programs.
>How-To-Repeat:
Try to compile a Fortran program. For example,
program hello
print*, 'Hello World!'
end
>Fix:
The following patch creates libfrtbegin. The file
libg2c/MAIN.c should be repo-copied to gnu/libfrtbegin.
