C++ PATCH to friendly_abort

[Jason Merrill <jason at redhat dot com>]

This patch brings C++ aborts in line with the backend, which replaces the
usual abort message with "confused by earlier errors".

2001-02-08  Jason Merrill  <jason@redhat.com>

	* typeck2.c (friendly_abort): Don't say anything if we have
	earlier errors or sorries.
