Gcc & WinMain@16

[Jorge Goncalvez]

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'

collect2: ld returned 1 exit status
make[1]: *** [dhcrelay] Error 1
make[1]: Leaving directory `/cygdrive/d/dhcp/code/dhcp/relay'

Why? Thanks.
