Python's makefile.  Currently only needed on Unix, so does nothing on
other systems.

that a particular compiler system depends on.  This consists of the
'set_executables()' and 'set_executable()' methods, and a few lines in
the constructor that expect implementation classes to provide an
'executables' attribute, which we use to initialize several instance
attributes.  The default implementation is somewhat biased in favour of
a Unix/DOS "command-line" view of the world, but it shouldn't be too
hard to override this for operating systems with a more sophisticated
way of representing programs-to-execute.

meant playing along with the new "dictionary of executables" scheme
added to CCompiler by adding the 'executables' class attribute, and
changing all the compile/link/etc. methods to use the new attributes
(which encapsulate both the program to run and its standard arguments,
so it was a *little* bit more than just changing some names).

I have this function, I'll probably allow quoted strings in config files too.

'remove_tree()' can cooperate with 'mkpath()' in the maintenance of
the PATH_CREATED cache: specifically, if a directory is created
with 'mkpath()', later removed with 'remove_tree()', and 'mkpath()'
is again requested to create it, then it would erroneously think
the directory already existed, because it was in the PATH_CREATED
cache.  The patch (slightly tweaked by me) fixes that.
