feenableexcept() not working with Cygwin on Appveyor

Hi there,

I am experiencing a very strange test failure, due to the fact that after a call to feenableexcept() (in a forked process) upon division by zero the signal is not raised:

should_crash___when__feenableexcept_was_called FE__with_Plugin FAIL

https://ci.appveyor.com/project/arstrube/cpputest/build/3.7.0-ci943/job/8waw4qdi72bowlec/tests

The same test is run successfully with MinGW:

https://ci.appveyor.com/project/arstrube/cpputest/build/3.7.0-ci943/job/4lhujta6nuey7apo/tests

What is even more strange, I have run these tests with Cygwin Gcc 4.8 and 5.3 on my local machine, and the test succeeds every time as expected. There is another test to verify the "division by zero" flag is set upon division by zero.

Any help would be much appreciated.

    The same test run in the parent process will end with a core dump (as expected, but not helpful ;-).

    So, how come no core dump occurs when run in a child process?
