This more simplifed version of your last testcase also catch -O2 problem:
#include
typedef int __attribute__((__mode__(__DI__))) off_t;
static long long min() throw() { return -9223372036854775807LL - 1; }

Hmm, this is the reduced testcase but it was not miscompiled as far as I can
see:
typedef int __attribute__((__mode__(__DI__))) __int64_t;
typedef __int64_t int64_t;
typedef int64_t streamoff;
typedef __int

In my opinion, this is definitely a (target dependent) code generation bug,
rather serious, if confirmed. As such, we should do our best to reduce it

At 2004-05-14 testcase failed
And i think this point to "The tree-ssa branch has been merged into mainline."

Hmm, it works for me on ppc-darwin with the mainline (20041215 and 20041214 and
