The @option{--enable-threads} option doesn't currently work, a patch is
in preparation for a future release. The @option{--enable-libgcj}
option is disabled by default: IRIX 6 uses a very low default limit
(20480) for the command line length. Although libtool contains a
workaround for this problem, at least the N64 @samp{libgcj} is known not
to build despite this, running into an internal error of the native
@command{ld}. A sure fix is to increase this limit (@samp{ncargs}) to
its maximum of 262144 bytes. If you have root access, you can use the
@command{systune} command to do this.
GCC does not correctly pass/return structures which are
smaller than 16 bytes and which are not 8 bytes. The problem is very
involved and difficult to fix. It affects a number of other targets also,
