+We support FreeBSD using the ELF file format with DWARF 2 debugging
+for all CPU architectures.  You may use @option{-gstabs} instead of
+@option{-g}, if you really want the old debugging format.  There are
 no known issues with mixing object files and libraries with different
-debugging formats.  Otherwise, this release of GCC should now match more
-of the configuration used in the stock FreeBSD configuration of GCC@.  In
-particular, @option{--enable-threads} is now configured by default.
-However, as a general user, do not attempt to replace the system
-compiler with this release.  Known to bootstrap and check with good
-results on FreeBSD 4.9-STABLE and 5-CURRENT@.  In the past, known to
-bootstrap and check with good results on FreeBSD 3.0, 3.4, 4.0, 4.2,
-4.3, 4.4, 4.5, 4.8-STABLE@.

-In principle, @option{--enable-threads} is now compatible with
-@option{--enable-libgcj} on FreeBSD@.  However, it has only been built
-and tested on @samp{i386-*-freebsd[45]} and @samp{alpha-*-freebsd[45]}.
-The static
-library may be incorrectly built (symbols are missing at link time).
-There is a rare timing-based startup hang (probably involves an
-assumption about the thread library).  Multi-threaded boehm-gc (required for
-libjava) exposes severe threaded signal-handling bugs on FreeBSD before
-4.5-RELEASE@.  Other CPU architectures
