Top-level configure.in patch

[Ben Elliston <bje@redhat.com>]

The ChangeLog entry for this patch ought to provide sufficient
explanation.  I have tested this with a wide variety of shells.  Okay
to commit?

2001-09-19  Ben Elliston  <bje@redhat.com>

	* configure.in (sparc-sun-solaris2*): Don't use /usr/bin/which on
	Solaris when testing for the /usr/ucb/cc compiler; it has incorrect
	semantics.  Use the shell built-in "type" command instead.
