Date: Wed, 01 Sep 2004 09:32:00 -0000 [thread overview]
Message-ID: <jer7pmwd0a.fsf@sykes.suse.de> (raw)
G++ 3.5 no longer treats _SC_GR0_OFFSET as an integral constant expression.
2004-09-01 Andreas Schwab <schwab@suse.de>
* sysdeps/unix/sysv/linux/ia64/sys/ucontext.h [g++ >= 3.5]: Use
__builtin_offsetof.
