thank you all. There was an incredible reason for the problem: ActiveTcl manipulated the TEXPATH variable and .exe was not reckognized eny more. Even when I reinstalled Tcl, their uninstaller did not restore this variable. After I restored the variable, everything worked again.
So this was not a Cygwin problem, sorry.
