Re: [rfa] *read.c -Wuninitialized fixes

[Andrew Cagney <ac131313 at cygnus dot com>]

And the patch ....
	* coffread.c (coff_symtab_read): Initialize
 	``fcn_first_line_addr''.  Check that the ``.bf'' always preceeds
 	the ``.ef'' info.
	* dbxread.c (find_text_range): Initialize ``start'' and ``end''.
