* configure.in: Prune nonexistent files from build_xm_file, xm_file, and host_xm_file lists. Warn unless they're $cpu/xm-$cpu.h. Don't generate *config.h here. AC_SUBST all variables needed to generate *config.h. * configure: Regenerate. * mkconfig.sh: New helper script, from code removed from configure.in. * Makefile.in: Zap all MALLOC variables - no longer used anywhere, and malloc.c doesn't exist. Substitute in variables needed to generate *config.h. Stop lying about the dependencies contained in CONFIG_H and GCONFIG_H. (HCONFIG_H, TCONFIG_H, TM_P_H): New variables. (config.h, hconfig.h, tconfig.h, tm_p.h, cs-config.h, cs-hconfig.h, cs-tconfig.h, cs-tm_p.h): New rules. (all .o): Add dependencies on $(HCONFIG_H), $(TCONFIG_H), $(TM_P_H), etc. as appropriate. * config.gcc: Zap references to deleted files. * ggc-none.c: Don't include rtl.h or tm_p.h. * config/i386/xm-beos.h, config/i386/xm-dgux.h, config/i386/xm-djgpp.h, config/i386/xm-dos.h, config/i386/xm-gnu.h, config/i386/xm-i386-interix.h, config/i386/xm-linux.h, config/i386/xm-linux.h, config/i386/xm-next.h, config/i386/xm-openbsd.h, config/i386/xm-sun.h, config/i386/xm-sysv3.h: Don't include i386/xm-i386.h. * config/elxsi/xm-elxsi.h, config/i386/xm-bsd386.h, config/i386/xm-i386.h, config/i860/xm-i860.h, config/i960/xm-i960.h, config/mcore/xm-mcore.h, config/mn10300/xm-mn10300.h, config/ns32k/xm-ns32k.h, config/pj/xm-pj.h, config/sh/xm-sh.h, config/v850/xm-v850.h: Delete (empty except comments, #includes of other deleted files, and macros used nowhere). cp: * Make-lang.in: Add dependencies on $(TM_P_H) as appropriate.
