yep, this is an advantage of a bytecoded program representation vs a 
traditional precompiled binary.

my case is sort of a hybrid:
generic HLL code should presumably be (reasonably) portable;
but, the program may still use ifdefs for OS-specific stuff (and may or 
may not be limited to targets with a compatible combination of ifdefs).

however, for the most part HLL code will likely depend some on the 
underlying app, so will generally only be as portable as the underlying 
app. Java, OTOH, is designed mostly for creating standalone apps (so, 
its portability is mostly bound by library and run-time features...).
