A quick note about running Apache under cygwin. If you just run
httpd2 on it’s own, you get an error about “invalid system call”. Very annoying.
A quick bit of googling reveals that you have to have something called
cygserver running. You have to set it up by running
cygserver-config the first time. After that, you just need to ensure that
cygserver is running.
Then, you can start Apache by saying
CYGWIN=server httpd2. And it all works!
