Hi Jakub,

Could we easily detect at resolve time whether a subroutine/function
makes any implicitly prototyped calls and limit this workaround to those
cases (i.e. only old-style Fortran)?  I've mentioned it in the PR, but not
sure how exactly to check that.


I think we could to that.  We could look at all the external symbols and
check with if (sym->attr.if_src == IFSRC_UNKNOWN) .

Let me think about this some more...

Regards

	Thomas
