$NetBSD: patch-br,v 1.2 2021/12/29 03:26:32 dholland Exp $

- Fix extra declarations of allocator functions that are out of sync
with the rest of the tree.

- Disable -fno-common on NetBSD (XXX why? The patch's original commit
message from 2002 says
    -fno-common is not necessary on NetBSD/alpha (or any ELF platform,
     really)
but I don't see why that's true given the associated comment, which
seems valid. (Or at least it is for alpha and mips, where non-library
code is built as PIC.)
