Currently sandbox configuration defautls to 64bit and there is no automation for building 32bit sandbox on 32bit hosts.
cpp does not know about target specification, code needs to be compiled to determine integer width.
Add a test program that prints the integer width, and a make target that aligns the sandbox configuration with the result.

This needs to be automatic, so that it builds the 32-bit version on 32-bit hosts, 64-bit version on 64-bit hosts.
See here for my attempt. I suspect it just needs your bits_per_long thing brought in, but in any case I hope it gives you inspiration.

Basically we should be able to build sandbox on any platform and it should just work, without manual configuration.
