Bounds check & cross-language

Nick,
thanks for the clarification (and sorry for the late feedback)

I think I see what you mean:
To do this properly I would have to annotate every Fortran routine
with string argument(s) with a hypothetical
"no-string-bounds-checking" option, if it is ever called from C. I
guess one could abuse !GCC$ ATTRIBUTES for this, but I hate the very
idea. So I guess I am stuck with the all-or-nothing approach of
disabling bounds checking for every source file with such routines,
right?

Cheers,
Dennis
