dmake warning question

[hsmyers]

I recently switched to dmake and I now get some warnings that I haven't seen before that are apparently harmless, but I'd still like to know what is going on... I've read the makefile (not my forte) and it would seem that these are part of an attempt to keep backwards compatibility alive and well. That however is just a guess and I'd appreciate a more knowledgeable monk's explanation? Here is the dos box text:

C:\>makefile
Set up gcc environment - 3.4.5 (mingw-vista special r3)

Looks good
