Pharas,

Larry is correct. You are not. Problems do occur with multiple copies of 
Cygwin1.dll on a system. We see it here all the time.

Cygwin relies on a shared memory segment and when there's more than one 
copy of the DLL on a given system, eventually a second one will get loaded, 
try to initialize itself and either fail or interfere with the one that's 
already loaded and initialized.

If you want to do this, it's no skin off our nose, but DON'T recommend that 
others do so.

Randall Schulz
