+We require binutils 2.11.1 (as of yet unreleased), binutils with
+binutils-2_11-branch tag after May 31, 2001 (as taken below), or newer.
+Previous binutils releases had a number of problems with DWARF2
+debugging information, not the least of which is incorrect linking of
+shared libraries.

+The version of binutils installed in /usr/bin is known to work unless
+otherwise specified in any per-architecture notes.  However, binutils
+2.11 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
+place.  FreeBSD 2.2.7 has been known to bootstrap completely; however,
+it is unknown which version of binutils was used (it is assumed that it
+was the system copy in /usr/bin) and C++ EH failures were noted.
+
+For FreeBSD using the ELF file format: DWARF2 debugging is now the
+default for all CPU architectures.  It had been the default on
+FreeBSD/alpha since its inception.  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 3.0, 3.4, 4.0, 4.2, 4.3 and 5-CURRENT.
+
+At this time, @option{--enable-threads} is not compatible with
+@option{--enable-libgcj} on FreeBSD.

 This port is very preliminary and has many known bugs.  We hope to
 have a higher-quality port for this machine soon.
