Quite a lot of churn on style, but lots of
good work refactoring complicated functions
and lots more unit-tests.
Thanks mostly to rillig at NetBSD
Some interesting entries from ChangeLog
o .MAKE.{UID,GID} represent uid and gid running make.
o allow env var MAKE_OBJDIR_CHECK_WRITABLE=no to skip writable
checks in InitObjdir. Explicit .OBJDIR target always allows
read-only directory.
o add more unit tests for META MODE

# Tests for the .elif directive.
|
|
#
|
|
# Misspellings of the .elif directive are not always detected. They are only
|
|
# detected if the conditional branch directly above it is taken. In all other
|
|
# cases, make skips over the skipped branch as fast as possible, looking only
|
|
# at the initial '.' of the line and whether the directive is one of the known
|
|
# conditional directives. All other directives are silently ignored, as they
|
|
# could be variable assignments or dependency declarations as well, and
|
|
# deciding this would cost time.
