Only useful for a non-portable language.

This does not establish that it would be useful for Java.

Lame reasoning.

How does presence in C# argue for or against the quality of a feature compared to its presence in Java?  It would be equally valid to argue that "ifdef" is bad because Java omits it.

Do try to avoid invalid reasoning, hm?

Still not speaking to whether "ifdef" is a good or bad feature.

Which "flexibility" causes infamous difficulties.

For certain values of "help".  "#ifdef" also horribly complicates C and C++ code and horribly damages readability.  This is a good thing?

You have it backwards.  "#ifdef" is a reaction to a fault, not a cause.

Since "standard JVM" doesn't run on Android, and Dalvik doesn't run elsewhere, I fail to see the problem.

J2ME is even less compatible with "standard JVM", whatever the heck that is.

Hopefully not very.

What is that "or such..." about, anyway?
