Yes, I know. This bug seems to only trigger on alpha, maybe because of some
alignment contraints or something – I really don't have any idea… – and thus
I can't find a workaround for it. (If you want to be nice to me, get an alpha
and try the diff below; I don't really want to have my sponsor upload another
package if it's not really working around the alpha bug.)
I can only suspect the bug is triggered by use of -std=gnu99 (the restrict
keyword makes the difference, which doesn't exist in c89), but not on all
architectures, but, on the other hand, the bug is actually in machine in-
dependent code and a bug in the libc headers.

Caveat: this is just a (possible) work-around, not a fix. But if it turns
out to indeed make mksh buildable on alpha again, I'll have an upgraded
mksh package uploaded.
