Really?

Since Cygwin "strace" is not a Cygwin program, it does not get Cygwin 
symbolic links resolved. Whereas on Unix or Linux, a symlink would be 
resolved by the kernel if it was used by strace and it (strace) would 
successfully get its target executed.

So wouldn't the behavior on Cygwin differ from a comparable invocation 
on Linux or Unix?
