dnl The support of GNU gcj for target-version and source-version:

- dnl gcj 3.0.4 to 4.1 does not have a way to specify the target-version.
+ 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 bytecode, which crashes with a VerifyError when executed by Sun Java
dnl 1.3.1. The bug is registered as java/7066, see
dnl http://gcc.gnu.org/bugzilla/show_bug.cgi?id=7066
- dnl FIXME: Check new versions of gcj as they come out.
+ dnl gcj 4.3 and newer has an option -ftarget=1.X.
dnl
dnl For gcj < 3.3, the source-version always is 1.3.
- dnl For gcj >= 3.3, the source-version defaults to 1.4; option
+ dnl For 3.3 <= gcj < 4.3, the source-version defaults to 1.4; option
dnl "-fno-assert" switches to source-version 1.3.
