That patch does restore i386-pc-solaris2.11 bootstrap, thanks.

Testsuite results are good, with two exceptions: for 32-bit compilation
(only, 64-bit is fine), two tests reliably time out at all optimization
levels:

WARNING: gm2/iso/run/pass/m2date.mod execution,  -O  program timed out.

WARNING: gm2/iso/run/pass/testclock2.mod execution,  -O  program timed out.

Running them under truss shows that the last system call each is

5032:   clock_settime(3, 0x080975F0)                    Err#1 EPERM [sys_time]

Running testclock2.mod under gdb shows

Thread 2 received signal SIGINT, Interrupt.

That year value seems very strange.
