# The "Native Win32" GNU Make contains quite some workarounds to get along with
# cmd.exe as shell. However it does not provide means to determine that it does
# actually activate those workarounds. Especially $(SHELL) does NOT contain the
# value 'cmd.exe'. So the usual way to determine if cmd.exe is being used is to
# execute the command 'echo' without any parameters. Only cmd.exe will return a
# non-empty string - saying 'ECHO is on/off'.
#
# Many "Native Win32" programs accept '/' as directory delimiter just fine. How-
# ever the internal commands of cmd.exe generally require '\' to be used.
#
# cmd.exe has an internal command 'mkdir' that doesn't understand nor require a
# '-p' to create parent directories as needed.
#
# cmd.exe has an internal command 'del' that reports a syntax error if executed
# without any file so make sure to call it only if there's an actual argument.
