6 # Various flavors of x86 UNIX executable/object (other than Xenix, which
7 # is in "microsoft"). DOS is in "msdos"; the ambitious soul can do
10 # Windows NT belongs elsewhere, as you need x86 and MIPS and Alpha and
11 # whatever comes next (HP-PA Hummingbird?). OS/2 may also go elsewhere
12 # as well, if, as, and when IBM makes it portable.
14 # The `versions' should be un-commented if they work for you.
