(portable to >DOS), "~dos" (sort of portable to DOS), or something like
"!dos" (not portable >to DOS), and not mentioning it results in nothing.

Just thought of something else: Might it be wise to have a "unique" token
which overrides all others? So for something like
`__djgpp_map_physical_memory' we can write:

@portability unique

and get

Portability: Unique to DJGPP

instead of

Portability: Not ANSI, not POSIX, not DOS, not Unix

If we go with the table format, this should probably print "no" in every
column, so that added targets don't require changes.

Or does someone have another idea?
