I know it's late in the game, but can this be fixed for 5.2 so I can build the new dhcpv6 correctly? Or should I find another way around this problem for 5.2? Thanks. pm-ack Upstream fix for the same issue: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=0df29025fd0379d5950d206314d0b10a2c8a9607 That patch is better, because it hides the global register variable altogether. We really don't want that in userspace. But it's also incomplete -- it should move gcc_intrin.h to 'unifdef-y' in the Kbuild file, since it now has __KERNEL__ bits to be removed. Adding the author of the upstream patch to the cc list. Doug, do you want to follow up on the additional fix suggested in comment #4? OK, so _that_ is what unifdef is for (I still feel like a newbie from time to time). I guess I didn't know how that stuff worked before but I see what is needed now. I will post a patch upstream.

RHEL5 version gcc_intrin.h fix, including Kbuild addition
Looks like there's a bunch of other stuff in there which shouldn't be visible in userspace too -- but maybe we don't want to be changing that for RHEL5. Will chase upstream. in kernel-$NEW_VER You can download this test kernel from http://people.redhat.com/dzickus/el5 in kernel-2.6.18-85.el5 You can download this test kernel from http://people.redhat.com/dzickus/el5 An advisory has been issued which should help the problem described in this bug report.

While trying to build the new dhcpv6 on RHEL 5.1, I hit a problem on ia64 with the gcc_intrin.h header file in /usr/include/asm. The problem is an invalid __attribute_used__. Removing it seemed to work for me: --- gcc_intrin.h.orig 2007-10-10 17:23:42.000000000 -0400 +++ gcc_intrin.h 2008-01-16 21:33:16.000000000 -0500 @@ -23,7 +23,7 @@ extern void ia64_bad_param_for_setreg (void); extern void ia64_bad_param_for_getreg (void); -register unsigned long ia64_r13 asm ("r13") __attribute_used__; +register unsigned long ia64_r13 asm ("r13"); #define __ia64_setreg(regnum, val) \ ({ \
