Ralph,
Are you sure this is a flex-generated file?
I am looking at opal/util/show_help_lex.l in the svn trunk and it
certainly looks human-generated to me.
Please clue me in if I am missing something.
The warning is from flex when processing the .l file, NOT from the
compilation of the flex-generated .c file.

We get that everywhere, unfortunately - it comes from flex and is outside our
control as the file it complains about is actually generated by flex itself.
Unfortunately, flex is no longer maintained, and so nothing has been done to
correct it.

I've not checked any other systems, but building the trunk on OpenBSD and
FreeBSD (w/ flex-2.5.4) I see the following:
LEX show_help_lex.c
"[srcdir]/opal/util/show_help_lex.l", line 65: warning, dangerous trailing
context
I found this message in the flex documentation, and it mentions that the POSIX
draft for LEX leaves such cases undefined.
