1880 dnl This macro searches for a GNU version of make. If a match is found, the

1882 dnl set to "#". This is useful for including a special features in a Makefile,

1884 dnl _cv_gnu_make_command is set to the command to invoke GNU make if it exists,
1885 dnl the empty string otherwise.
1887 dnl Here is an example of its use:
