From 740895462f700e34f3a5959802f4631e11817c86 Mon Sep 17 00:00:00 2001

Subject: [PATCH] 	* gdbtk.c (gdbtk_init): Change gdbtk_lib_tmp and
 gdbtk_file to be 	dynamically allocated, rather than fixed size.  Pass
 "gdbtcl" to 	ide_initialize_paths to match installed directory name.  If
 IDE, 	use auto_path to search for main.tcl. 	* Makefile.in (install-only):
 If ENABLE_IDE, install from gdbtcl2 	rather than gdbtcl.
