Attached is my cygcheck.out (some private info is redacted).

I just did a compare by running the same "make" build using cygwin 
(rxvt), msys (also rxvt) and cmd. With msys and cmd I see "system" 
process running occasionally and for a short time at a maximum of 20% 
cpu. Usually I see the "make" process or just "system idle" and the 
build completes in about 22 seconds.

With cygwin/rxvt, as described previously, I see "system" process at 
40-50% (usually 50%) and nothing else using cpu comes to the top. The 
same build takes about 14 minutes on cygwin.

Running in the standard cygwin shell (not rxvt) the time is the same, 14 
minutes compared to 22 seconds under msys/rxvt and cmd shells.

I removed the 2nd cygwin1.dll in the path that it warns about but it 
made no difference.

Is there anything evident in the cygcheck that accounts for the extreme 
running of the windows "system" process with cygwin active?
