[PATCH] Patch that breaks the gnumach build


From: Marin Ramesa
Subject: [PATCH] Patch that breaks the gnumach build
Date: Sun, 1 Dec 2013 10:47:53 +0100

I need some help. I'm trying to fix a GCC warning by modifying the
struct dev_ops in device/conf.h. I need the definition of io_req_t
to do that. But when I include device/io_req.h from device/conf.h 
the build breaks with this error message:

In file included from ../vm/pmap.h:45:0,
                 from ../vm/vm_object.h:49,
                 from ../vm/vm_page.h:40,
                 from ../device/io_req.h:41,
                 from ../device/conf.h:35,
                 from ../device/dev_hdr.h:64,
                 from ./machine/io_perm.h:26,
                 from ../i386/i386/tss.h:32,
                 from ../i386/i386/thread.h:43,
                 from ./machine/db_machdep.h:37,
                 from ../ddb/db_access.c:34:
../kern/thread.h:81:2: error: unknown type name "pcb_t"

gnumach has been configured with --enable-kdb.

kern/thread.h already includes i386/i386/thread.h which defines the
pcb_t, so I don't understand why GCC fails with this error message when
everything is OK. 

Does anybody have any idea what is happening?
