--- Comment #1 from Martin Sebor <msebor at gcc dot gnu.org> ---
Confirmed.  It's somewhat related to pr97882 in that the warning depends on the
result of comp_target_types() which considers int (*)(double) compatible with
int(*)() but int (*)(float) incompatible.  The warning is issued in
convert_for_assignment().

Interestingly, on Godbolt, both Clang and ICC behave just like GCC.  Only MSVC
warns for both assignments.
