Emacs uses a combination of these two techniques, but until now we
managed to have almost the same workarounds and headers for both MinGW
and MSVC.  E.g., unistd.h is not used at all (although MinGW does have
it); instead, all the necessary stuff is defined in the
Windows-specific config.h file.  There's a Windows-specific nt/
subdirectory where we put headers and source files that define
suitable replacements for missing Posix headers and functions.

It would make sense to have MSVC-specific replacements there as well,
once it becomes impossible to keep it and MinGW together.

Thanks for the feedback.
