* 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
+ end_of_text_address.
+ * config/gould/tm-pn.h: Add comment regarding END_OF_TEXT_DEFAULT.
+
+ * 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.
