OK. This does make sense for me. Would you like to prepare the patch?

HAVE_UNIX_SERIAL looks ugly for me. I'd like to know how big the differences
are. But hey, we can use #if (defined WIN32) || (defined CYGWIN)

I don't thing so. But when you use
#if (defined A) || (defined B) || (defined C)
It is convinent to have some macro for it to write:
#ifdef ABC
