This script is for a Plan9 instance.

If it is a rc(1) script, this does not mean that the compilation and
installation is totally native: it still uses APE, but switches when
needed.

Be sure to run me in a dir where there is enough place for the
sources unpacked (40 Mb will do; I will _not_ remove the bundle).

During the build, don't be afraid of some compiler warnings: these
are purely cosmetic ones, because the translation of Pascal in C
don't put extra braces when indenting if/else; or because D.E. Knuth 
and Silvio Levy have written the CWEB programs so that they can compile
even on pre-ANSI C compilers (old prototypes).

Don't worry: if something is really wrong, the build fails...

I will build in SAVE_SPACE mode, requiring the minimal amount of
place.
