Hi Guys,

  I am forwarding this email for Ben Elliston, who is having some
problems with ORBS...

Cheers

------------------------------------------------------------------
The following patches add CGEN support to the opcodes
Makefile/configury.  I have not included patches for generated files
like `configure'. 

2000-07-28  Ben Elliston  <bje@redhat.com>

	* Makefile.am (CGEN, CGENDEPS, CGENDIR, CGENFLAGS): New.
	(run-cgen, stamp-m32r, stamp-fr30): New targets.
	* Makefile.in: Regenerate.
	* configure.in: Add --enable-cgen-maint option.
	* configure: Regenerate.
