Cygwin (gnu) path problem, cannot find g++/make...

[crea]

Installed cygwin. bin folder: C:\cygwin\bin

if I do mount in bin, I get: c:/cygwin/bin

if I do path in dos promth (I did put this path to path-variable obviously) 
I get: c:\cygwin\bin

So everything should be ok? But I get error "'make' is not recognized as an 
internal or external command..." if I try to use gnu compiler. So obviously 
it cannot see the bin folder. Anybody know what to do? thanks
