Comment 2 Agostino Sarubbo gentoo-dev

Found the following implicit function declarations in configure logs:

config.log:816 - __va_copy

Comment 3 NHO 2025-01-04 22:59:56 UTC

check for __va_copy
It's provided explicitly by gcc, but not by clang
Should be safe to ignore.

Comment 4 NHO 2025-01-04 23:05:26 UTC

Correction, explicitly provided by glibc, but not musl.
There's define guard that skips __va_copy if va_copy is defined.
also, va_copy is never used explicitly
