Re: please make byte compiling during bootstrap take advantage of make -j

[Richard M Stallman]

One idea is to divide the .el files according to the first letters
of their names.  You could divide them into 26 categories this way,
and have 26 targets which could be run in parallel in any manner.
Since each target would compile a substantial number of files,
this would not greatly increase the overhead of starting processes
for compilation.
