Actually, mman.h uses caddr_t, not addr_t, at least in the cygwin 1.3.15
system I have installed. Nothing in /usr/include appears to use addr_t.
My typedef of addr_t is for 64-bit int.

Yes, I renamed all references to addr_t to a different name.
It's just a nuisance and appears to be unnecessary name polution.
