1995-07-06 Patches from Jerry Blakely <gerry_blakley@wellfleet.com>:Ian Lance Taylor1-2/+11
* as.c (listing_filename): New static variable. (show_usage): Mention -a=file. (parse_args): Support = option of -a to set name of listing file.

1992-04-27use -K for broken word option rather than -k which means pic to sun asK. Richard Pixley1-5/+8
