Issue: net-dialup/ppp-2.4.9-r8 fails to compile (CLANG-STRICTER-SYSTEM).
Discovered on: amd64 (internal ref: clang-stricter_tinderbox)

NOTE:
(CLANG-STRICTER-SYSTEM) in the summary means that the bug was found on a machine that runs clang with stricter mode

This machine uses clang with CFLAGS/CXXFLAGS=-Werror=implicit-function-declaration -Werror=implicit-int -Werror=incompatible-function-pointer-types

Is this still the case with more recent versions?

All versions in the tree build with gcc-14 and clang-18.
