These changes clean things up a bit, and improve Solaris cross

support when using /opt/SUNWspro/SC2.0/acc.

Tue Nov 10 09:50:25 1992  Ian Lance Taylor  (ian@cygnus.com)

	* obj-coffbfd.c (fill_section): set STYP_NOLOAD bit for .bss
	section.

	* atof-ieee.c, atof-ns32k.c, tc-*.c: made EXP_CHARS, FLT_CHARS,
	comment_chars, line_comment_chars and line_seperator_chars
	consistently const, and always initialized them.  Included read.h.
