[svn-r4744] 
Purpose:
	Bug Fix
Description:
	There were weird "throw()"s which were being placed into the
	configure script. Some C++ compilers were barfing on this syntax
	(which was akin to "extern int exit(int) throw ();" wonder why?).
Solution:
	Ran a different autoconf on the configure file which I'd downloaded
	from ftp.gnu.org. It doesn't have those "throw()"s anymore
Platforms tested:
	Linux
