Re: V3 and cross-compiler (AIX 4.3 64-bit mode)

[David Edelsohn <dje at watson dot ibm dot com>]

	The following patch invokes mknumeric_limits with the
cross-compiling flag set if it exited with a failure.  Would something
like this be acceptable an a way to have V3 configure try a little harder
to finish configuring in the face of gen-num-limits failing to run?

Thanks, David


	* configure.in (mknumeric_limits): Try using cross-compiler mode
	if initial attempt failed.
