It's not an issue of whether Cygwin supports RPMs.  It's an issue of 
trying to install a Linux executable on Cygwin.  It doesn't matter 
whether it's packaged in an RPM, it's still a Linux binary, not a Cygwin 
binary.

From the Cygwin FAQ (which I strongly recommend reading):


Where is glibc?

Cygwin does not provide glibc. It uses newlib instead, which provides 
much (but not all) of the same functionality. Porting glibc to Cygwin 
would be difficult.


THC-Hydra claims that it builds fine on Cygwin.  Does it not?
