Ok, much of this has been addressed by others, so I won't comment further.

Reorganizing stuff MIGHT be sensible, but it seems pretty sensible now
with the must change, check, and only change if you know what's going on
and then subdivided within that by VMS and UNIX.

No, order has nothing to do unless multiply defined... (see below)

The last will most likely take preference, but when you compile, the
pre-processor will usually spit out a warning like: 

Warning: foo.h: 84 BAR was redifined.
         foo.h: 32 Location of previous definition.

The compiler flags and such might affect which definition it takes, but
I'm 90% sure that the last would override the first, and compiler flags
would just make a redefinition an error instead of a warning.
