	While it is possible to combine egcs, binutils, newlib, gdb,
etc. into a single tree.  Including gdb seems to be discouraged because
both it and binutils rely upon bfd in subtle ways.  One can run into
problems because of source skew between binutils and gdb as only one
package can be the source for the bfd library.  binutils is more integral
in the toolchain, so it usually is better to include binutils in the
"single tree" and build gdb separately.

	Cygnus does not have this problem because they can access their
development tree in which bfd is not forked for a particular package.
