Interesting patch for linc

[Peter Williams <peterw ximian com>]

Hi everyone,
	I needed this patch to get my linc to compile; it's a bit interesting
because it exposes a behavior change (bug?) in autoconf >= 2.50. It
seems that 

configure.in:

	VAR=value
	AC_SUBST(VAR)
	VAR=new_value

file.in:
	
	@VAR@

will give you 'value', not 'new_value'. I can't figure out why, but I
figured I would give people a heads-up as this is a kind of odd thing
that might cause lots of head-scratching some time later.

Anyway, Michael, or someone else with authority, may I commit?

Peter
