Removed psignal/siginfo.h - problematic and unnecessary. check-in: 6848d4da90 user: geraint@users.sourceforge.net tags: origin/merging-ode2odes-exe, trunk

SIGINT (C-c C-c) now causes simulation data to be dumped to MTT.core.
SIGQUIT (C-c C-\) as for SIGINT, then raises default SIGQUIT.
SIGFPE as for SIGINT, then raises default SIGABRT. check-in: 25ab7dc08c user: geraint@users.sourceforge.net tags: origin/merging-ode2odes-exe, trunk
