And so we add to PATH and still have a problem if the lapack and
openblas versions are different.  Adding to PATH doesn't fix the issue
and if I add the openblas version before lapack then lapack suffers and
vice-versa. This is the reason we've put DLL in the /usr/bin directory
because adding to PATH is meaningless.

Perhaps
https://msdn.microsoft.com/en-us/library/windows/desktop/hh310513(v=vs.85).aspx
should be used in the main function or a Cygwin API developed to do
that.  Or fix lapack to name it's library with a different version id.
If there are API/ABI differences, then -0 isn't correct since the two
cannot overlay each other.
