Subject: [musl] [PATCH 2/2] include <stdc-predef.h> in <features.h>
Date: Thu, 15 Apr 2021 21:35:21 -0300
Message-ID: <20210416003521.2147-2-ericonr@disroot.org> (raw)
In-Reply-To: <20210416003521.2147-1-ericonr@disroot.org>

GCC source code does contain a function to pre-include the
<stdc-predef.h> header for glibc targets, but even so glibc still
includes it in their own <features.h> header. furthermore, even if GCC
implemented this for musl targets, it is still necessary for other
compilers or previous versions of GCC.
