Actually, you will like this news even better.  GCC apparently handles the
idirafter differently for darwin than it does for others.  I was messing
around and realized that I had missed the obvious.  Jam is actually calling
/usr/bin/c++ which obviously has a target of darwin.  I pulled out the build
command and prepended the generated/cross-tools/bin/i586-pc-haiku- path so
it was actually *using* the cross compiler, and that seems to resolve both
problems.  :)

How do I make it so that jam prepends the target system to all of the build
tools instead of calling my native ones?
