This is because C frontend implements this by calling
cgraph_mark_node_if_needed and the function ends up not being needed for LTO or
whole program.
This is a hack, since even if I make things needed, whole program

gcc incorrectly handles the following code. The underlying problem is that gcc
does not require the template keyword in certain places where it should
require it. The side effect is that gcc refuses to parse valid code that looks
like a template parameter list but really is not. The first

Best imho to put in the cast to quash the warning.
To be warning free -- esp. given how close you already are.
Sometimes I think warning-free across a range of compilers is untenable.

Note: The ABSTRACT, the INTERFACE (vs. host-association), and the
use-association of i_f do not seem to play a role.
In particular for p:
sym-attr.pure == 0
sym-attr.proc_pointer == 1

The problems seems to be that resolve_symbol is called later than the
resolve_formal_arglist check for pureness, i.e. one first checks whether p
is
pure before one copies the attr.pure
