 # First make a best effort at recognizing x86 CPU type and leave it in X86CPU.
 # If we fail, set X86CPU to UNAME_MACHINE
+#
+# DJGPP v2 (or 2.03 at least) always gives "pc" for uname -m, and the
+# OEM for uname -s.  Eg. pc:MS-DOS:6:2 on MS-DOS 6.21.  The list of
+# possible OEMs is in src/libc/dos/dos/getdos_v.c of djlsr203.zip, but
+# just pc:*:*:* seems ok.
