GNU Make stop with an error message when
trying to parse a Makefile which is 
using the MSDos text-file format.

Ex.:

makefile:<NR>: *** missing separator.  Stop.

Where <NR> is the last line in the
makefile.

In order to get make to parse the file 
you need to strip the makefile for
^M (Ctrl-M)'s and ^Z (Ctrl-Z).

My testing indicates that the only problem is the ^Z character at the
end of the file.  MS-DOS text files with CR-LF pairs but WITHOUT ^Z
at the end are processed by Make OK.
