[committed] Fix style issue pointed out by Bernhard in my recent change

[Jeff Law]

Bernhard pointed out that we should be using


machine_mode <variable>

rather than

enum machine_mode <variable>

in one of my patches.  I guess old habits die hard.

Anyway, this trivial patch fixes the nit.  I'll try to remember to start
omitting the "enum" "class" and "struct" thingies more appropriately :-)
