I should clarify this by saying that you can have the same code for both
Windows and Linux as long as you don't do anything Windows or Linux
specific (POSIX-compliant code should compile cleanly on both
platforms). You will have to compile it once for Windows and once for
Linux becuase of the different executable formats. You can't take a
Linux executable and run it on Windows or vice versa.

You can get GCC for Windows as well as Linux. I run it under Cygwin all
the time. Under Windows it will produce Windows executables.

There may be a way to cross-compile for Windows under Linux with the
right parameters passed to GCC but I've never looked in to that or tried
it.
