* On architectures using ELF, and conditionally on those in transition, rename _ASM_LABEL(cerror) and _ASM_LABEL(curbrk) to _C_LABEL(__cerror) and _C_LABEL(__curbrk) (or their respective architecture-specific equivalents) to avoid possible name clashes with identifiers used in user applications. * Do the same for minbrk on all architectures to avoid a GCC-specific (and on ELF architectures effectively useless) symbol reference renaming in MI code. 1999-01-15 01:48:18 +03:00			`/* $NetBSD: pipe.S,v 1.5 1999/01/14 22:48:21 kleink Exp $ */`
