Compiler warnings when compiling -- Gentoo

[arran4]

When I build using this:
https://github.com/arran4/arrans_overlay/blob/main/app-text/jbofihe/jbofihe-0.43.ebuild

Portage tells me that these are severe warnings:

Yep! This code is very old. Most of it is no younger than the year 2001 or so. Updating code of that age is a substantial undertaking.

Having said that, it does in fact run fine most of the time.

haha Yeah I know. But no one else reported this, its' here if anyone ever picks it up again.
