My impression of "interpretation" was aimed at the back-end, where
tokenized (virtual machine...) code has to be brought to a physical
machine, with a specific firmware (OS). Then the real back-end has to
reside on the target machine and OS, fully detached from the preceding
compiler stages.

Then, from the compiler writer viewpoint, it's not sufficient to define
a new language and a compiler for it, instead it must placed on top of
some popular "firmware" like Java VM, CLR or C/C++ standard libraries,
or else a dedicated back-end and libraries have to be implemented on
each supported platform.

My impression was that the FSF favors C and ./configure for "portable"
code. That's why I understand that any other way is easier for the
implementation of really portable software, that deserves no extra
tweaks for each supported target platform, for every single program. Can
somebody shed some light on the current practice of writing portable
C/C++ software, or any other compiled language, that (hopefully) does
not require additional human work before or after compilation for a
specific target platform?
