Reporter: Adam Chasen
Priority: Minor
There are warnings (which are treated as errors due to -Werror) which fail the
build in:
/bin/sh ../libtool --tag=CC --mode=compile gcc -DHAVE_CONFIG_H -I. -I..
-I../include -O2 -g -D_FORTIFY_SOURCE=2 -fstack-protector
-D_LARGEFILE64_SOURCE -ansi -Wall -Werror -Wno-implicit-function-declaration
-D_GNU_SOURCE -MT dir_handler.lo -MD -MP -MF .deps/dir_handler.Tpo -c -o

There may be other errors in util dir, I removed -Werror from configure in
./util to continue build
