Hi, I checked the mailing list but I didn't find some informations except the
use of -lm.
So i tried to port the dhcp version 2 of the ISC but I have some compilation
errors:
$ make
Making all in common
make[1]: Entering directory `/cygdrive/d/dhcp/code/dhcp/common'
make[1]: Nothing to be done for `all'.
make[1]: Leaving directory `/cygdrive/d/dhcp/code/dhcp/common'
Making all in server
make[1]: Entering directory `/cygdrive/d/dhcp/code/dhcp/server'
make[1]: Nothing to be done for `all'.
make[1]: Leaving directory `/cygdrive/d/dhcp/code/dhcp/server'
Making all in relay
make[1]: Entering directory `/cygdrive/d/dhcp/code/dhcp/relay'
/bin/gcc -o dhcrelay dhcrelay.o ../common/libdhcp.a
/usr/lib/libcygwin.a(libcmain.o)(.text+0x6a):libcmain.c: undefined reference to
`WinMain@16'
collect2: ld returned 1 exit status
make[1]: *** [dhcrelay] Error 1
make[1]: Leaving directory `/cygdrive/d/dhcp/code/dhcp/relay'
make: *** [all] Error 1
Why? Thanks.

## Porting::
#
# For each supported operating system, there is a block of text below
# beginning with #--os-name-- and ending with #--os-name--. Between
# these delimiters are assignments, commented out, which define the
# Makefile variables required for that operating system.
#
# The configure shell script figures out what operating system it's
# being run on and then runs Makefile.dist through a sed script which
# removes the comment characters from the appropriate set of
# assignments, and writes the output to Makefile.
