[Bug libfortran/20246] New: libfortran: iargc off-by-one error

[anlauf at hep dot tu-darmstadt dot de]

Hi,

there is an obvious off-by-one error in gfortran's implementation of
the IARGC() intrinsic:

program iargc_test
implicit none
integer :: iargc
print *, iargc ()
end program iargc_test

% gfortran iargc_test.f90 && ./a.out

prints 1 instead of zero.

Cheers,
-ha
