It turns out Ant's invocation of the javac compiler had nothing to do
with standard extensions being suppressed.
It was which JVM was being used to start ant.
If I execute java by hand from my bash shell (this is on Windows),
bash's PATH picks up /jdk/bin/java.exe, which pays attention to standard
extensions.
But the ant.bat file runs under an MS-DOS command window, and
apparently picks up /windows/java.exe, which doesn't pay attention to
standard extensions.
What's /windows/java.exe? Beats me. When run /windows/java -version,
it says it's java version "1.3.0", so Sun's J2SE 1.3 installer put it
there---but I don't know the reason.
Take care.
