Unfortunatly Euphoria doesn't provides conditional include :(
That's a feature that would be quite useful for example to have a program to
run either under DOS32 or WIN32, autodetecting it's enviorment and
dinamically loading the appropiate routines. There's still a problem with
the interpreter (ex.exe or exw.exe), but before that we need conditional
inclusion.

Anyway I think you may be able to simulate the effect using the function
routine_id(). It's complex and difficult to maintain. Personally I have
never used routine_id (except for some experimetal WIN32 tasks).
