+ * Makefile.in (config.status): Depend on development.sh.
+ (aclocal_m4_deps): Add libmcheck.m4.
+ * acinclude.m4: Include libmcheck.m4.
+ * configure.ac: Source development.sh instead of setting
+ 'development' here. --enable-libmcheck/--disable-libmcheck code
+ factored out to GDB_AC_LIBMCHECK. Run it.
+ * development.sh: New file.
+ * libmcheck.m4: New file.
+ * configure: Regenerate.
