# intel:  file(1) magic for x86 Unix
#
# Various flavors of x86 UNIX executable/object (other than Xenix, which
# is in "microsoft").  DOS is in "msdos"; the ambitious soul can do
# Windows as well.
#
# Windows NT belongs elsewhere, as you need x86 and MIPS and Alpha and
# whatever comes next (HP-PA Hummingbird?).  OS/2 may also go elsewhere
# as well, if, as, and when IBM makes it portable.
#
# The `versions' should be un-commented if they work for you.
# (Was the problem just one of endianness?)
