I'm porting a program that sets errno if an operation fails.  However, in
the B20.1 errno is a macro that dereferences the pointer returned by a
function #define errno (*__errno())

What is the proper way to set errno in cygwin?

Based on comments I've read in the headers, it appears that the following
will work:

_REENT->_errno = xxx

Is this correct, or is there a more compatible or preferred way of doing this?
