[M3commit] CVS Update: cm3

[Jay K]

I thought it was too, before I looked at it.
Could be that head and release are very divergent.
I didn't look at release, oops.
  I probably will "soon".


The config files are "partly part of the compiler", and partly system-specific.
 So they might have to be updated with the compiler.


Perhaps we can have cm3.cfg.user or cm3.cfg.local, that we never edit,
and maybe we should constrain it, like very line
must have an equals sign, and if it has a percent, percent must follow equals.


e.g.
m3back_flags = "-custom"
SYSTEM_CC = "custom" % comment blah blah
SYSTEM_LIBS{"LIBC"} = "custom"
SYSTEM_LIBORDER += [custom]

But that might not be flexible enough.

Another option is that cm3.cfg file do like:
if exists("cm3.cfg.user.first")
  include("cm3.cfg.user.first")
end
...
if exists("cm3.cfg.user.last")

  include("cm3.cfg.user.last

end



which is infinitely flexible and not well defined.
 Even limiting to assignments is not well defined.
 You know, there's an interface somewhere in there, but it isn't well specified. My fault.
  I let things evolve and get discovered gradually, sometimes hard to know ahead of time what the result will be.
 

I've made changes since 5.8.6 released such that config files from prior to 5.8.6 will not suffice.
I can undo that, but there is an important policy and architecture question.
