188c635fbb * Makefile.in (INTERNAL_CFLAGS): Add ENABLE_CFLAGS.
* fork-child.c (fork_inferior):  Add call to
	TARGET_CREATE_INFERIOR_HOOK to allow target specific code to get
	control just before the new process executes it's first instruction.
	* remote-mips.c (mips_initialize):  Cleanup a bit.  Don't try to
	receive a packet at first.  This speeds up initialization a lot.
	Use TARGET_MONITOR_PROMPT instead of "<IDT>".
	(common_breakpoint):  Use rresponse instead of rerrflg to inspect
	error code.
	* symfile.c (syms_from_objfile reread_symbols):  Call
	TARGET_SYMFILE_POSTREAD to allow target specific code to get
	control after reading new symbols.
	* target.h:  New macros TARGET_SYMFILE_POSTREAD, and
	TARGET_CREATE_INFERIOR_HOOK.  See above for descriptions.
	* config/mips/{irix5.mh nm-irix5.h}:  Delete nm-irix5.h.  Make
	NAT_FILE point directly at ../nm-sysv4.h.
	* config/mips/{mipsm3.mh nm-m3.h}:  Delete nm-m3.h.  Make
	NAT_FILE point directly at ../nm-m3.h.
	* config/mips/{mipsv4.mh nm-sysv4.h}:  Delete nm-sysv4.h.  Make
	NAT_FILE point directly at ../nm-sysv4.h.
	* config/mips/nm-mips.h:  Improve comment at top of file.
	* config/mips/tm-mips.h (TARGET_MONITOR_PROMPT):  Change
	definition into a proper string.

	* configure configure.in:  Add support for --enable-gm.
	(mips*-*-magic*):  Change target from magic to idt.
	* eval.c expprint.c expression.h parse.c remote-mips.c utils.c:
	Change GENERAL_MAGIC_HACKS to GENERAL_MAGIC.
	* magic.c magic.h:  Update files from GM.
	* config/mips/magic.mt:  Delete.  No longer necessary now that we
	use --enable mechanism.
	* config/mips/tm-idt.h:  Add GM stuff needed for remote GM box.
	* config/mips/tm-irix5.h:  Add GM stuff needed for native Irix box.
	* config/mips/tm-magic.h:  Move up to config/tm-magic.h.  Move all
	platform specific stuff into tm-irix.h and tm-idt.h.  Add defs for
	TARGET_SYMFILE_POSTREAD and TARGET_CREATE_INFERIOR_HOOK.

180fd370b1 Ideally the "remote-mips.c" prompt spotting code should be updated to
spot different prompts at run-time, so as to avoid having target
specific versions of gdb. This is a pending TODO.
