_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.
