It might be worth considering using the test from pdksh.

I've made a standalone version and cleaned it up a bit.  The executable 
is the same size, but it also supports the ksh -O, -G, -L, -nt, -ot, and 
-lt primaries.

Another nice thing is that it uses a recursive descent parser, so it's 
actually easy to follow what the code's trying to do.
