\awk 'BEGIN {print x}' x=foo
\should print 'foo' and start reading stdin, but it prints an empty
\line and terminates.

Known bug: the variable is only set AFTER the first input line has been
read. :-(
Work-around:

	(echo ''; cat) | awk 'NR == 1 {print x}' x=foo -

Don't forget to add the `-' (for stdin), else you'll step into another
bug... :-(
