C++ compilers on Linux supporting 64bit architecture?

Sam,

I work at a company where we use wxWidgets (http://www.wxwidgets.org/) 
for all of our GUI development in C++.  All of our apps our built to run 
on 32-bit Windows using Visual Studio .NET 2003 and both 32-bit and 
64-bit versions of Fedora using GCC.  Fedora, via yum, provides a 
packaged version of wxWidgets, but we usually build it from the 
wxWidgets SVN repository.

No code modifications are required to build the apps on Windows vs. 
Fedora, so I guess I would disagree with your statement "any GUI 
libraries, they are obviously not available on Linux", but I would agree 
that most projects do not consider cross-platform GUI development when 
they are initially developed, so they are not using a library like 
wxWidgets.

Hope that helps with any cross-platform GUI development anyone out there 
is considering.
