Cygwin programs need to be able to load cygwin1.dll
You need to add C:\cygwin\bin to the Windows PATH; then cygwin1.dll
will be found even when running programs from the command prompt.
This is a step you have to perform manually; the installer does not do it.

There are some potential name clashes between Windows programs and
Cygwin programs; e.g. find
If you put C:\cygwin\bin before C:\windows\system32 and type just the
name of the program, you'll get the Cygwin version even from a Windows
prompt (which is what I usually do, because I can't remember using the
Windows version of find). If you put C:\cygwin\bin after
C:\Windows\system32, you'll get the Windows version.

>From a Cygwin shell, you get the Cygwin version by default (unless you
change the path in your bash startup script), because Cygwin does some
magic with the path to get its own bin directory to the front.

Hope this helps,

Csaba
