kerberos related warning - Mailing list pgsql-hackers

I just noticed this warning:

gcc -O -Wall -Wmissing-prototypes -Wpointer-arith -Winline
-Wdeclaration-after-statement -Wendif-labels -fno-strict-aliasing -g
-pthread  -D_REENTRANT -D_THREAD_SAFE -D_POSIX_PTHREAD_SEMANTICS -fpic
-DFRONTEND -I. -I../../../src/include -D_GNU_SOURCE  -I/usr/include/et
-I../../../src/port  -c -o fe-auth.o fe-auth.c -MMD
fe-auth.c: In function 'pg_fe_getauthname':
fe-auth.c:573: warning: passing argument 1 of 'free' discards qualifiers
from pointer target type

I think the attached is the appropriate fix. Any objections?
