ISC dhcp server on NetBSD

[dhcp.50.CHRIS94561 at spamgourmet.com]

  I'm currently trying to compile the ISC DHCP server found at
(http://isc.org/sw/dhcp/) from source but for unfortunately I'm running
into some problems. Obviously this is possible since the dhcpd binary that
comes on the NetBSD rescue disk is the isc server. Here is the compile
error:

gcc -g  -I/share/projects/dhcp/dhcp-3.0pl2
-I/share/projects/dhcp/dhcp-3.0pl2/includes -Wall -Wstrict-prototypes
-Wno-unused -Wno-comment  -Wno-uninitialized -Werror
-Wimplicit-function-declaration -Wpointer-arith -Wcast-qual  -Wcast-align
-Wwrite-strings -Wconversion -Wmissing-prototypes  -Wmissing-declarations
-Wnested-externs  -pipe    -c parse.c
cc1: warnings being treated as errors
parse.c: In function `parse_lease_time':

prototype
*** Error code 1

Stop.
make: stopped in /share/projects/dhcp/dhcp-3.0pl2/work.netbsd/common

This error doesn't come up on the Linux compile. Best I can tell time_t
is signed on both systems. Why the warning? I know this is relatively
minor and I can remove "-Werror" to avoid it but I'd like some clarity.
