The system call puts the time in a pair of registers, not in the
timeval structure. Add code to move the time to the structure, so
programs see the correct time, not garbage. This fixes our example
programs that use the time as a random seed.
These produce Mach-o executables for Mac OS X on Intel or PowerPC
processors. Our code generator for PowerPC (mach/powerpc) still has
bugs. Some examples seem to run, but startrek crashes. Our code
generator for Intel (mach/i386) is better.
There is a problem with job control. If you run paranoia or startrek,
then suspend the job (^Z) and resume it ('fg' in bash), then read(2)
might fail with EINTR.
