* Add correct $NetBSD$ headers everywhere. * Remove $Id$ headers. * Support LIB_SCCS in all files. * Use local labels where ever possible. * Use cpufunc.h instead of __asm__ when possible. * Access labels with _C_LABEL and _ASM_LABEL. * Always set errno by calling cerror. * No more FRAME/EMARF. * No more SVC, use SYSTRAP instead. * Use "$Masqueraded: as XXX $" to show e.g. memcpy compiled as bcopy. * Rewrite vfork to work even whith a "real" vfork system call. * Make cerror take care of _REENTRANT.
