MinGW doeas EXACTLY this.
But, of course, you won't get all the nice things you get with cygwin.
With MinGW you'll only gat what Microsoft provided, plus some things 
volunteers added in libmingw*, I guess.

How DID you run configure ? What IS your platform ?

Use standard Cygwin.
Build you executable.
Then right click on it, and select "View dependancies".
Grab all the cyg*.dll your file depends on, and put them in the same dir as 
your executable.
ZIP it (or RAR it, or ACE it, tar.gz'ip, or wahever :-), and distribute it.

NOTE: Your program license will have to comply with that of the libraries 
you link with.
If you GPL it, you'll probably be fine with whatever comes with cygwin.
This is, of course, no legal advise, just a "common sense" thing.

No, it will use the system C libraries (glibc on Linux, newlib on cygwin, 
wincrt.dll for mingw, I guess).

Yes, pascal comes in a different package, not with GCC.

I hope this helped to clarify things a bit. If you need more infos, have a 
look at MinGW docs and links, and then mail back.
I'll be happy to help.
