# pgfun.c forward-declares pgfun1/pgfun2/pgfunplot with empty parens
# (K&R) then calls them with arguments. gcc 16's default (-std=gnu23)
# treats `()` as `(void)` and rejects the calls with 'number of
# arguments doesn't match prototype'. Pin to gnu89 so K&R survives.
# verified 2026-05-10 against 2.35.
