https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=de829b7a5819e93bb69eb0894e519b3bfebfd676 appears to have broken compilation with clang. Removing the "append-cflags -std=gnu17" line fixes it.
Comment 1 Mike Gilbert gentoo-dev 2024-12-04 04:43:21 UTC 
Looks like the crazy homebrew build system passes CFLAGS to the C++ compiler. Nasty.

    app-text/ghostscript-gpl: work around broken build system
    
    The homegrown Makefiles pass CFLAGS to the C++ compiler.
    Add "-std=gnu17" to CC to avoid an error with clang++.
