[URGENT] PHP as an apache module on windows under cygwin

Hi! I am very new to both windows and PHP (coming from a solaris environment), so please excuse me if the answer is glaringly obvious. I have built and installed apache (1.3.23) on a windows 2000 Professional (SP2, build 2195) box with cygwin (1.3.9, I believe). The build supports many of the modules included with apache and supports shared objects. Some of the modules are built as shared objects. Is there a way to use the win32 binaries with apache? I keep getting a win32 error when apache tries to dlopen the php module. If not, how can I build php 4.1.1 as a shared object for apache? Please assume no knowledge on my part. TIA Stephano Mariani
