- * Hack to work around the AIX C compiler's brain-damaged error messages
- * so that emacs can parse them. It runs /bin/cc as a subprocess, and
- * tries to rearrange the error messages so that (a) each message contains
- * both the filename and line number where the error occurred, and (b)
- * the error message(s) for a particular line get displayed *before* the
- * line itself.
- *
- * to compile:
- * lex aixcc.lex
- * cc -o aixcc lex.yy.c
