# Tests for the special .MAKEFLAGS variable, which collects almost all

# the environment variable MAKEFLAGS (without leading '.').
# When options are parsed, the option and its argument are appended as
# separate words to .MAKEFLAGS. Special characters in the option argument
# are not quoted though. It seems to have not been necessary at least from
# 1993 until 2020.

# Tests for the special MAKEFLAGS variable.
# Tests for the special MAKEFLAGS variable, which is basically just a normal
# environment variable. It is closely related to .MAKEFLAGS but captures the

# read.
# TODO: Implementation
.MAKEFLAGS: -d0
# The unit tests are run with an almost empty environment. In particular,
# the variable MAKEFLAGS is not set. The '.MAKEFLAGS:' above also doesn't
# influence the environment variable MAKEFLAGS, therefore it is still
# undefined at this point.
