[Ace-users] Unable to run simple ACE programs in cygwin

I am running a simple client and server ACE programs on cygwin.
Compilation does not give any error. No error is shown at runtime
also, but it does not seem to run either. When I run the server, it
exits immediately. it does not block on 'accept' . 'echo $?' on the
shell shows return code as 128. Here are the things I tried:

1. 'ps -ef | grep <server / client>' does not show anything.
2. I ran make on the 'inserver' and 'inclient' programs in the
'examples' directory, ran the server and client, that also did not
give any result (and 'ps -ef' did not show any result here too).
3. I put in a couple of 'printf' at the beginning of 'main', this too
did not get printed at run-time. But commenting out all code except
the 'printf' worked.

Can someone please help?

I am compiling the code using this command:
g++ <server / client program name> -I/cygdrive/c/cygwin/ACE_wrappers/ /

Other details:

ACE version is 5.5.9.
