Just before you spend too much time on it, the algorithm itself used
by the bound checker has been said to be not 100% reliable.  I don't
know why and where though.  My impression is that it's okay for the
few test cases given in boundtest.c, however not ready for compilation
of real programs (probably not even tcc itself).

I tested on windows and the pointer is set there which could mean there
is something specific going on with ELF symbols or relocation.
