[linux-lvm] avoid ptrdiff_t-related format-mismatch warnings on x86_64

[Jim Meyering]

Building from cvs, I saw about a dozen of these warnings:

    config/config.c:493: warning: format '%d' expects type 'int', but argument 5 has type 'long int'

This fixes them:

2007-04-26  Jim Meyering  <jim at meyering.net>

	* lib/config/config.c (match): Use %ld, not %d, to match argument
	of type ptrdiff_t.
	(_type): Likewise.
