dnl gcj 3.0.4 to 4.2 does not have a way to specify the target-version.
dnl It always assumes target-version=1.4 but labels the class files as 1.1.
dnl One consequence of this is that gcj compiles GetURL.java to invalid

dnl
dnl For gcj < 3.3, the source-version always is 1.3.
dnl For 3.3 <= gcj < 4.3, the source-version defaults to 1.4; option
