32 bit or 64 bit Cygwin? Works for me, I get

$ gfortran MyTest.f90 -o MyTest -llapack -lblas

$ ./MyTest
Printing the results
           0
End printing

So no "compilation finished" message. Might you have some other
version of gfortran on your path? I believe cygcheck.out would
list some of this information. Other things to check:

which -a gfortran
which -a cygblas-0.dll
