So far, I have windows/ibdiag_osd.h, ibdiag_windows.c, and
windows/cl_nodenamemap.h.

My goal is to have the ib-diags support both Windows and Linux, so Windows files
are related in that respect.  Making an exception for the build files is
reasonable IMO, given the WinOF build environment.

unistd.h is an 'osd' type file, so I think it makes more sense to isolate it to
an osd related area.  But if you really prefer, I can abstract these.  (Windows
provides an errno.h file, so at least there's some precedence.)

opts_map is declared as const - (i.e. my compiler whined at me)

I'll see if I can get this to work.  My quick test gave me compiler option
conflicts, so I'll have to look into this more.
