entries.

        * dbxread.c: More comment cleanups.

        to the live range list until the entire range stab has been parsed.
        (get_substring): Remove duplicate declaration.

Thu Jul 25 19:41:31 1996  Fred Fish  <fnf@cygnus.com>

for a rather huge set of changes.  I was going to put them here, but it
made cvs dump core.  :-(

3a179be149 * Makefile.in (os9kread.o): Remove dependency on partial-stab.h.
* dbxread.c (read_dbx_symtab end_psymtab), partial-stab.h:  Don't
	use partial_symtab->textlow==0 as a flag, as 0 is a legitimate
	text address.  Use a seperate flag (textlow_not_set) instead.

	* mdebugread.c xcoffread.c:  Define textlow_not_set for
	partial-stab.h.
	* stabsread.h (end_psymtab):  Add textlow_not_set arg to prototype.
