Subject: unconditonally define alloca as __builtin_alloca
X-Git-Tag: v1.2.0~22
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=a56ec7e8e27c4e8bb7aa7d612bf382b4bafb132f;p=oweals%2Fmusl.git

unconditonally define alloca as __builtin_alloca

This enables alternative compilers, which may not define __GNUC__,
to implement alloca, which is still fairly widely used.

This is similar to how stdarg.h already works in musl; compilers must
implement __builtin_va_arg, there is no fallback definition.
