# NOTE: Don't add useless checks. autoscan detects this and that, but don't

# let it confuse you. For example, we don't care about checking for behavior

|
|
# of malloc(), stat(), or lstat(), since we don't use those functions in

|
|
|
|
# a way that would cause the problems the autoconf macros check.
