I'm working on a port of GNU make 3.75 using the Minimalist GNUWIN32
headers **and** compiler and I have no problems what so ever with
CR-LF vs CR only. It seems to be a problem with the way the makefile
is opened. 

It might just be something as simple as including the fopen-... headers
from libiberty to solve this problem. Other files (and headers) would
also be of interest in the special case of make-3.75 (I'm thinking of 
pexecute.[ch] and their associated files).

Who is 'in charge' of GNU make-3.75 ? I'd like to share some thoughts 
with him.

Just some thoughts.
