- Sort the includes of pack.c, moving sys/*.h files near the top. - Add a couple of missing #include lines, and remove the need for custom -include options in the CFLAGS of the test Makefile. - Remove the ad-hoc 'all' target, but keep its 'regress' bits for testing. - Convert the ad-hoc 'clean' target to proper CLEANFILES stuff, so that the normal bsd.prog.mk machinery can clean up. - Use `make -V .OBJDIR' to detect the place where 'pack' lives, so that regress.t works both with and without 'make obj'.
