error when compile checkpassword-0.90.tar.gz

help,

when I compile checkpassword-0.90.tar.gz with
make setup check

in the end I have this:

../compile str_start.c
../makelib byte.a byte_copy.o byte_cr.o byte_diff.o \
str_chr.o str_len.o str_start.o
( ( ./compile tryshadow.c && \
../load tryshadow -lshadow ) >/dev/null 2>&1 \
&& echo -lshadow || exit 0 ) > shadow.lib
rm -f tryshadow.o tryshadow
( ( ./compile trycrypt.c && \
../load trycrypt -lcrypt ) >/dev/null 2>&1 \
&& echo -lcrypt || exit 0 ) > crypt.lib
rm -f trycrypt.o trycrypt
../load checkpassword prot.o unix.a byte.a `cat \

collect2: ld returned 1 exit status
make: *** [checkpassword] Error 1

what can I do?

You have gcc version 3.+ You must replace extern int errno; with
#include <errno.h>

Unless you follow the recommended patches at
http://www.qmail.org/top.html you will run into the same problem when
you attempt to compile the other DJB applications.
