Alexey, you're right! That was :-) Looking at the call_dsrs() in that
time, I suddenly did think, Hm, the call_dsrs() is declared as static,
it would be called from cyg_interrupt_call_pending_DSRs(), but I haven't
such an implementation... So, I was thinking, That call is the kernel's
deal...

I just missed what HAL interrupt_end() does it for any kernel-less
configuration, and the hal/common/current/tests/intr.c is a pretty much
advocacy. I ought remember what the eCos `intr' test quite works without
a kernel package. Thanks, for a brainwashing!
