Is the C code compiled for the same platform ECL runs in, or for a different
one?

The problem right now is that ECL's compiler uses information that is
hardcoded in the runtime to take decisions about the generated C code. Thus,
the code generated for a given platform can only be reliably produced by an
ECL built for that same platform, which is why the possibility of
cross-compiling ECL exists.

If the target compiler and the original ECL are built for the operating
system then you do not need to go through such complicated paths and it
typically suffices to change the compiler name c::*cc* and other special
variables which are internal to the compiler (see cmp/cmpdefs.lsp to find
out the names)
