GnuWin32 or Cygwin - from a programmers point of view

For a programmer with Linux skills and a love of the command line, what is better to use on Windows - Cygwin or GnuWin32?

I tried to find a good comparison or a list of differences but couldn't find anything remotely complete. Also, I wondered w开发者_如何学运维hether this should be a superuser.com question, but decided against it, because I'm asking precisely for use of the tool for a programmer.

I'd like to know the common pitfalls and restrictions of each of the solutions. Interoperability with windows is an important issue, for my main development is done in MSVC...

It is absolutely no contest

GnuWin32 does not include Bash

This is a critical part of the Cygwin distribution. Switching from cmd.exe to Bash was a huge boon to my productivity. cmd.exe is cripped in comparison to Bash.

GnuWin32 is old

Many program go years without being updated.

• tar 2003
• coreutils 2005
• zlib 2005
• make 2006
• wget 2008

I would not use GnuWin32 unless I had no other choice.
