Log Message:
Apply fixes derived from the HEAD branch of X.Org (6.8.99) to address
problems noted in CAN-2004-0914:

    Multiple vulnerabilities in libXpm for 6.8.1 and earlier, as
    used in XFree86 and other packages, include (1) multiple integer
    overflows, (2) out-of-bounds memory accesses, (3) directory
    traversal, (4) shell metacharacter, (5) endless loops, and (6)
    memory leaks, which could allow remote attackers to obtain
    sensitive information, cause a denial of service (application
    crash), or execute arbitary code via a certain XPM image file.

Bump PKGREVISION to 4.  Since this is a security-related fix, also
bump the BUILDLINK_RECOMMENDED version for this package.
