I don't understand what "this issue" you are referring to. Is it the possibility
that the build machine and the target machine have different C compilers,
or the need for a C compiler at all? If the former, I don't see why
having the switch compilers from build to target should be a problem,
If the latter, if a machine does not have a C compiler, then it cannot
install a standard source distribution anyway. Has anyone ever used
such a machine to compile Mercury programs?
