The version of binutils installed in @file{/usr/bin} is known to work unless

+2.11 or greater is known to improve overall testsuite results.
For FreeBSD 1, FreeBSD 2 or any mutant a.out versions of FreeBSD 3: All
configuration support and files as shipped with GCC 2.95 are still in

+In principle, @option{--enable-threads} is now compatible with
+@option{--enable-libgcj} on FreeBSD@. However, it has only been built
+and tested on i386-*-freebsd4.5 and alpha-*-freebsd5.0 and important
+test suite failures remain. Multi-threaded boehm-gc (required for
+libjava) exposes severe threaded signal-handling bugs on FreeBSD before
+4.5-RELEASE. The alpha port may not fully bootstrap without some manual
+intervention: gcjh will crash with a floating-point exception while
+generating @file{java/lang/Double.h} (just copy the version built on
+i386-*-freebsd* and rerun the top-level gmake with no arguments and it
+should properly complete the bootstrap). Other CPU architectures
+supported by FreeBSD will require additional configuration tuning in, at
+the very least, both boehm-gc and libffi.
