Looks good mostly.
Historically, switching windows code to use "W" APIs has been a big TODO,
but was waiting for Win98 de-support.
Please spell correctly:
If errno and GetLastError are two separate error notification systems, how
do you know which one corresponded to the last failure? E.g. if the last
failure only set errno, won't the error message be via GetLastError(),
which is likely to be stale?
