Subject: krb_udp.c warning fix
X-Git-Tag: openafs-devel-1_5_67~67
X-Git-Url: http://git.openafs.org/?p=openafs.git;a=commitdiff_plain;h=d616d1ee99794525aa2d778d11552c1986007ebb

krb_udp.c warning fix

This file generates a warning because the left side of a variable
assignment is commented out.  Keep the effect of the line
(incrementing packet) but remove the unused casting and
reference, and remove the comments that date from the original
IBM source.
Leave a new comment in place in case the information is useful.

Adjust the Makefile and README.WARNINGS to account for the change.
