Parsec 1.1RC2 build fails on Macos about parsec

[anta5010]

The same issue is seen when building Parsec 1.0.0 on Macos.
But, no issues when Parsec 1.1.0RC2 built in an Ubuntu 22.04 container with clang 14.0
So, it looks like Macos only issue

I've got a similar issue when tried to build parsec in Yocto with clang 15.0.2 and musl instead of libgc:
