>Description:
        drscheme (version 370) is currently marked BROKEN (Fails
        to install (signal 11)).  On my machine, if BROKEN is
        commented out of the Makefile, then it doesn't even
        build.  Previous versions have built successfully under
        FreeBSD-6, and version 3.99.0.4, from the PLT subversion
	repository also builds and installs just fine.

>How-To-Repeat:

	This is the script that I've been using to try building
	outside of the ports tree.  Ports has ver=370.  The
	current release is 371, and 371.3 is available as a
	pre-release, which is what I've used here.  If the
	maintainer could upgrade, as well as apply this patch,
	that'd be neat, too.

The second patch, to sighand.c copes with the change in
delivered signal on a memory page fault, in FreeBSD-7.  The
first patch, to wx_keym.cxx seems to relate to some extra
strictness in the xform.ss program.
