# $NetBSD: varcmd.mk,v 1.7 2023/04/07 05:54:16 rillig Exp $

#
|
|
# Test behaviour of recursive make and vars set on command line.
|
|
#
|
|
# FIXME: The purpose of this test is unclear. The test uses six levels of
|
|
# sub-makes, which makes it incredibly hard to understand. There must be at
|
|
# least an introductory explanation about what _should_ happen here.
|
|
# The variable names are terrible, as well as their values.
|
|
#
|
|
# This test produces different results if the large block with the condition
|
|
# "scope == SCOPE_GLOBAL" in Var_SetWithFlags is removed. This test should
|
|
# be rewritten to make it clear why there is a difference and why this is
|
|
# actually intended. Removing that large block of code makes only this test
|
|
# and vardebug.mk fail, which is not enough.
