This is typical.  It happens for a lot of non-Fortran programs also. 
start.S comes from glibc and is linked into every program.

The only thing you're missing is that GDB does not support F90.  No
one's given serious time to the Fortran support in a few years now,
either.  So it's assuming that Fortran -> Fortran77, at a guess.
