It does not look like that this is the same trouble I reported
last week (failed compilation on Alpha of slhc.o from Linux kernel
sources).  I just tried egcs-19980727 snapshot, where regmove.c is
modified, and the reported problem persists.

I did not try yet if the other reported by me problem (series of kernel
"oops" on shutdown for a "snapshot-compiled" kernel) remains or not.
