Update GCC in Cygwin?

[Chuck Chopp]

Are there any issues associated with updating applications that were 
included as part of the Cygwin installation?

I'm just beginning to get familiar with Cygwin, and I have some C++ code 
that is primarily being built using Visual C/C++, but I also need to test it 
for portability for use with GCC on Linux and Mac OS X.  Initially, I was 
thinking of just using GCC under Cygwin to do the basic compile to make sure 
that I get a clean compilation pass before I set up actual target systems to 
do a full build on.

What I noticed, though, is that the GCC version that's included with Cygwin 
is older than what will be used on Linux & OS X, so I was interested in 
whether or not there's problems with taking an updated distro kit for GCC on 
  a Linux x86 platform and installing it within Cygwin.

Is this something that should be do-able w/o problems?  Or, do I need a GCC 
build that's made explicitly for use in Cygwin?


TIA,

Chuck
