Eli,

I checked the past postings and this = one slipped=20 between the cracks. In the last posting of the previous thread you asked = for me=20 to give more details which I am now doing 7 months = late.....

The original posting with this issue = was in the=20 following thread:

http://www.delorie.com/djgpp/mail-archives/br= owse.cgi?p=3Ddjgpp-workers/2002/05/29/06:33:31

This also occurs with make 3.79.2a1, which is where I first seen = the=20 problem and it is also in 3.80.

Should I report this to the make maintainers or is it a DJGPP = specific=20 problem or should I just ignore this warning?
