Please zap the ipc_test references in the Makefile's "make clean" target
too.
I realize you probably left those in intentionally, but I don't think
it's a good idea for clean targets to remove files that weren't built.
I think such leftover operations are time bombs: someday, many years
from now, that might remove a file somebody wanted.
