these two compilers are cygwin ones

this is not.

Take cygwin out of the loop, what is the answer of
time_ifort.exe in cmd ?

I am still baffled why the same source runs fine for gfortran and g95. Notice however that for these compilers, the _date_ and _time_ functions are not defined. Hence the preprocessor exclusion in the source.

I doubt cygwin is intercepting a not cygwin program call to MS ssystem
