Bug#696757: ecl and SIGNALS

[Christoph Egger]

Hi!

  As suggested by Michael Banck on IRC I've been looking at Signals used
by both parts to see if they e.g. battle over SIGUSR?. However libgc
seems to use 32+{5,6} as signals on x86 FREEBSD __GLIBC__ at
least. Petr, Steven: any idea why this is? Are these signals fine for
kfreebsd glibc (signal.h says only 32,33 are reserved). ecl seems to use
SIGRTMIN+2 internally which should not be a problem. I failed to see so
far what signals are used by libgc on linux
