You're quoting a message from me which does not mention 1.15.20.  It is
1.*5*.20.

There is no reason to argue about this when a simple removal of the
version is all that I'm asking for.  Changing the "for Cygwin
1.15.20(sic)+" to "when it is supported by the compilation environment"
would be sufficient.

Ok then I withdraw my suggestion.  Your code is fine as is.
