and "post_add_symbol_hook". These hooks are called before we begin reading
symbols, and after we finish.
(generic_load): Use new symbol reading hooks and get rid of compiler warning.
* gdbtk.c (gdbtk_init): Add hooks for pre- and post-symbol reading.
(gdbtk_pre_add_symbol): New function: the pre-add-symbol hook.
(gdbtk_post_add_symbol): New function: the post-add-symbol hook.
(find_file_in_dir): New function. Moved the guts of gdb_find_file_command
into here to allow its use by others.
(gdb_loc): Use find_file_in_dir to return the real path to the file
(or "N/A" if we can't find it).
* configure.in (TIX_LIB_EXT): Define new variable for those special cases
when TCL_SHLIB_SUFFIX is not enough to specify the dependency.
* configure: Regenerate.
