+ * Makefile.in (TARGET_FLAGS_TO_PASS): Pass down LD_FOR_TARGET and
+ NLMCONV_FOR_TARGET. (SUBDIRS): Add nlm target.
+ * configure.in (powerpc-*-netware*): Automatically configure nlm
+ subdir.
+ * nlm/Makefile.in: Add {CC NLMCONV LD}_FOR_TARGET. Remove alpha
+ specific stuff. Make things more configurable.
+ * nlm/configure.in: Add powerpc-*-netware* target. Use
+ gdbserve.mt/cpu.c/cpu.h for target stuff. Get rid of tm/xm/nm.h
+ files.
+ * nlm/gdbserve.c: Move Alpha specific stuff into other files.
+ Remove lots of architecture-specific stuff.
+ * nlm/gdbserve.def: Add new imports.
+ * nlm/ppc.c, nlm/ppc.h: New files that contain PowerPC specific code.
+ * nlm/prelude.c: Don't include libhooks.h, get rid of call to
+ register library.
+ * nlm/prelude.o: What was this doing here?
