Er, yes. I have this in

Sorry I wasn't clear; I'm trying to use javac from the Sun JDK, not gcj.

I tried changing to


I never use $(JDK_JAVAC) other than to test that the variable is
non-empty. And this in my

  JAVAROOT = $(top_builddir)/java
  noinst_JAVA =

Works if WITH_JDK is true; but if WITH_JDK is false, javac still gets
called, but with no source file arguments. I don't want this to happen
since someone may have configured --without-jdk because they don't have
it on their system.
