byte compiling

["T. V. Raman" <raman@xxxxxxxxxxx>]

I do not recommend this method of compiling --
it will introduce inadvertant dependencies between the .el
files as they are compiled with  resulting bugs that might
prove hard to locate.
The current build technique builds each .el file in a clean
environment.
