[darcs-users] darcs patch: Generate SRC_DIRS programmatically. (and 8 more)

[Trent W. Buck]

This is a subset of my outstanding 50-or-so makefile fixes, the last
two patches in this list, plus their dependencies.  Eric has already
reviewed some (all?) of these and recommended they be applied.

I re-recorded the last two patches because they conflicted with some
patches from the sprint, and I'd like them to be applied soonish
because I suspect they will continue to cause (spurious) conflicts.

  * Generate SRC_DIRS programmatically.
  
  The -name sys -prune -o ... -print part is a hack to skip the
  src/win32/sys, which is probably safe to include in the list, but I
  didn't want to take any chances.

  * Obviate SRC_DIRS altogether.
  
  Note that find -delete would be better, but it is not standard:

  * DARCS_FILES_DEPS is never bound, so don't evaluate it.

  * Tweak C_OBJS declaration.

  * Replace procedural := with declarative =.
  
  When you do "x = a b" in make, it doesn't get evaluated until you
  actually attempt to refer to $x in a rule, because make is an expert
  system.  The reason := exists is because if you do
  
      f = $(shell really-slow-command)
  
  and then try to build a bunch of object files, $f will cause
  really-slow-command to be run separately for each one.  Since we're
  just doing internal stuff like $(patsubst), we don't need := and using
  it makes it harder to reason about the system, because it's no longer
  declarative.

  * Miscellaneous refactoring.

  * Generate DARCS_FILES by blacklist, not whitelist.
  This attempt is far from perfect, but at least it works.

  * Make .hs of trivial .lhs files.

  * Make .hs.in of trivial .lhs.in files.
