# Tests for the special .CURDIR variable, which is initially set to the
|
|
# canonical path of the current working directory, when make started.
|

# In all normal situations, the current directory exists, and its name can
|
|
# be resolved. If not, make fails at startup.

#
|
|
# It would be possible on some systems to remove the current directory, even
|
|
# while a process runs in it, but this is so unrealistic that it's no worth
|
|
# testing.
