Zabbix 1.1 build on windows/cygwin

[eldnah]

I am a bit stuck on the make portion of building the zabbix server. I am running ./configure --with-mysql --enable-server.
Which returns fine, then when I run make I get:
...
make[4]: Entering directory `/cygdrive/c/installs/zabbix/zabbix-1.1/src/libs/zbx

Any help would be appreciated.

Thanks
