https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: app-text/enchant-2.3.4 has implicit function declarations in configure logs (GCC-13-SYSTEM). Discovered on: amd64 (internal ref: gcc13_tinderbox) NOTE: (GCC-13-SYSTEM) in the summary means that the bug was found on a machine that runs gcc-13 but this bug MAY or MAY NOT BE related to the new compiler See also: https://bugs.gentoo.org/898488#c4.

Looking at the gnulib macro, I think this is a false-positive. The configure result is: > checking for alignas and alignof... yes, <stdalign.h> macros so it's properly detected. The gl_ALIGNASOF macro checks the test program first *without* including stdalign.h and then again *with* it if the first test failed. This seems like it's going to hit a lot of packages...
