Single Unix Specification and sniff test* of a few operating systems
says SIGFPE (floating point exception) results in a core, but we don't
install the sig_coredump handler for this signal along with SIGSEGV,
SIGILL, SIGBUS, etc.
Attached patch allows CoreDumpDirectory to work its magic in response to SIGFPE.
* looked at: AIX5.3, RHEL4, Solaris8, HPUX 11iv1,
