You have hit some ugly point between commits. Bad luck :-)

mmap is used in ECL to help in delaying interrupts. The trick is simple: ECL
gets an interrupt while executing a C function that can not be interrupted,
it marks (using mmap) the Lisp environment as read-only, ECL tries to write
to the environment after the C function finished, this causes a signal and
now it can be processed together with the pending interrupts. But this only
works when mmap implements interrupts with information.
I am really surprised that the Sun platform does not support SA_SIGINFO :-/
Would one need additional compiler flags to allow the headers provide this
facility?
