===================================
Windows 2000 Professional
CYGWIN_NT-5.0 1.5.4(0.94/3/2)
gcc version 3.3.1 (cygming special)
===================================

I compiled some program with Cygwin and Mingw32 interfaces.

$ g++ fib.cpp -o fib_cyg

$ g++ fib.cpp -mno-cygwin -o fib_nmg

$ time -p fib_cyg th 10000 > zzz
real 0.48
user 0.44
sys 0.03

$ time -p fib_nmg th 10000 > zzz
real 0.39
user 0.02
sys 0.04


We can see that user-time-used for executable file with Mingw32 interface is nearly equal 0.
It seems that that is not in line with the reality.

Any explanation?

P.S. I think the problem doesn't depend on the specific program.
     Nevertheless the attachment contains the fib.cpp file.
