RE: gnubol: IBM flags nested conditionals as error (RC=8) but recovers OK

["William M. Klein" <wmklein@ix.netcom.com>]

Oh boy,
 PLEASE don't try and match what IBM does for E-level errors.  The following
is what IBM says about E-level compiler errors,

"An error-level message indicates a condition that is definitely an error.
The compiler has attempted to correct the error but the results of program
execution might not be what you expect.  You should correct the error."

See:

http://www.s390.ibm.com/bookmgr-cgi/bookmgr.cmd/BOOKS/IGYPG204/2%2e1%2e7%2e1%
2e2

If you start trying to match their "error recovery" for E-level messages, you
are going to find life VERY difficult.
