Log Message:
Add distfile patch:
	- pass -Wall, use <ctype.h> correctly, use standard headers, etc.
	- fix up illegal printf usage (existing behavior was undefined)
	- roll in the bug fix from patch-ac
	- declare own functions properly, avoiding LP64 issues

Bump PKGREVISION as some of this fixes bugs.

Prompted by (and includes changes from) PR 49347 from Rob Quinn.
