# FUNC_MKDIR_TAKES_ONE_ARG defines MKDIR_TAKES_ONE_ARG if, well, mkdir takes
# one arg (instead of 2 like it does on POSIX systems).
#
# Take from a phantom file contributed to GNU "patch" that I can't find
# anywhere except in mailing lists.  Attributed to Mumit Khan and Paul Eggert.
#
# Note that if you don't have the correct #includes in the test-compile code,
# the compiler will give a missing-prototype warning but will succeed.  Yuck!
