Apparently GCC quadmath does not exist as far as clang is concerned? Not familiar with Gentoo's x86_64-linux-quadmath/ perl directory but overall this just seems to be the compiler being deeply unhappy with the usability of perl in a code snippet.

[Comment 9 Sven Wegener 2022-10-05 19:04:12 UTC]

It looks like perl has been built by gcc with USE=quadmath enabled. As quadmath is gcc-only, building with clang fails, as the quadmath includes are in gcc's include directories.
