Because egcs added these switches as -mk6. The rationale was that no -m
option includes the vendor name (-mintelpentium?).

There are definitely problems with 1.1.3. this is related to my backport
of snapshot features (hey people: thats why I don't like backporting fixes
;)

Interesting. Are you sure? I ask because you seem to infer from your
example that the amdk6 is counted as a i486 architecture, which you can't
(since then there shouldn't be a difference between both options).

The pentium, the i486 and the amdk6 share the same instruction set
architecture (with regards to a compiler). Both pentium and amdk6 use the
same instructions (i.e. -march=i486)

an url where I can fetch that program (and te version numebr you used)
would be perfect unless you know the file that is responsible.
