[Click] AlignmentInfo Question

[Eddie Kohler]

Roberto,

It looks like recent GCCs caught a mistake in one of our configuration test 
programs.  As a result, Click's configuration process was not able to 
determine whether a machine was indifferent to alignment, at leas ton my 
machine.  This should be fixed now.

If the updates don't help you, send your generated config.h, and tell us what 
type of machine you're running on.

Eddie
