In principle, if you use only the compiler wrappers for your lam
installation,don't select any separately built 32-bit .o files, and
don't issue the -m32 option (for gnu compilers; each compiler has a
different scheme), you should be OK. I may have missed it, but I didn't
see an indication of whether you are using only a consistent set of gcc
64-bit compilers.
