[Distutils] generating pyc and pyo files

29 Mar 1999

      When should the .pyc and .pyo files be generated during the
install process, in the "build" directory or the "install" one?

I ask because I've been looking into GNU autoconf and automake.
They compile emacs lisp code (.el->.elc) in the build dir before
the actual installation, and it might be nice to follow their
lead on that, and it would ensure that the downloaded python files
are compileable before they are installed.

OTOH, I know the normal Python install does a compileall after
the .py files have been transfered to the install directory. 

Also, looking at buildall, it doesn't give any sort of error
status on exit if a file could not be compiled.  I would prefer
the make process stop if that occurs, so compileall needs to exit
with a non-zero value.   Attached is a context diff patch to
"compileall" from 1.5.1 which supports this ability.  I can send
the full file as well if someone wants it.
