I just want to point your attention tp https://bugs.gentoo.org/971955.Perhaps for 2.4.0 or 2.5.0 this could be fixed, as it seems there's old-style in the codebase that Clang22 does not want to accept any more. Copy of excerpt from the bug:
Hi Fabian,I've taken a look, and this looks like a bug in Mutt's configure.ac file. It looks like you are actually passing '--without-bundled-regex', but the configure.ac has incorrect code to process that and turns on the bundled regex.c anyway!
We are currently in a code freeze for the 2.4.0 release, but this bug is important enough that I'll get this fixed and include it.
In the mean time, the fix on your end would be to completely remove the '--without-bundled-regex' from your configure script arguments. The default has it turned off, so you don't need to pass it. I suspect your libc has a working version, and regex.c won't be compiled anymore.
Fixing regex.c is a bigger issue, but I'll work on that after the 2.4.0 release.
