Subject: [PATCH] Fix build for sys-devel/reflex

When LEX=reflex is used, this compiling calc.lex fails with a
implicit function declaration error when
Werror=implicit-function-declaration. (Like with clang16)

Bug: https://bugs.gentoo.org/884361
PR to upstream this: https://github.com/FeCastle/tiptop/pull/9

Signed-off-by: Pascal Jäger <pascal.jaeger@leimstift.de>

Clang16 will not allow implicit function declarations by default
