* dbxread.c: New variable lowest_text_address.

	(record_minimal_symbol, read_dbx_symtab): Set it.
	(read_dbx_symtab): Use lowest_text_address + text_size instead of
	end_of_text_address.
	* config/gould/tm-pn.h: Add comment regarding END_OF_TEXT_DEFAULT.

+       * dbxread.c: New variable lowest_text_address.
+       (record_minimal_symbol, read_dbx_symtab): Set it.
+       (read_dbx_symtab): Use lowest_text_address + text_size instead of

+
+       * dbxread.c (end_psymtab): Remove old and commented out
+       capping_global and capping_static.  Fix comments regarding
+       N_SO_ADDRESS_MAYBE_MISSING to match the real name of the macro.
+
        * parser-defs.h: Add "extern" to start of variable declarations so
        we don't end up with commons.
        * parse.c: Define these variables.
