Comment 2 Eli Schwartz gentoo-dev 2024-07-10 01:43:59 UTC 
This is actually "just" a GCC 14 implicit function declaration. But without that compile failure it had mismatched types due to incorrect implicit prototype...

    x11-libs/libgxim: backport gcc 14 fix for implicit-function-decl
    
    Upstream has fixed this in 2018 but simply not released a new version:
    https://bitbucket.org/tagoh/libgxim/commits/274976ff39d9142169a18655f5013e66233ac9c8
    
    Due to the implicit function declaration, compilation fails on gcc 14.
    On gcc 13, instead, there is an lto-type-mismatch because the K&R C
    style incorrect prototype was... incorrect and mismatched the required
    types. :)
    
    The same upstream commit also includes an unrelated fix for a different
    build issue: -Werror=format-security.
