These patches are not quite right (for example, they kill some
functionality on VxWorks).  The right approach, if you must is to
define inhibit_libc, if you want to go this route.  Though, I prefer
the autoconf approach.  No one has contributed that yet.

Sure, we all do!  But we through experience we already kew that
--with-headers is more than just a good idea, it is required.

http://egcs.cygnus.com/install/configure.html has a note about this,
but it is obscure.  Maybe the phrase `THIS OPTION IS REQUIRED when
building a cross compiler' should be added?

Hope this helps.
