RE: [xml] strace reports SIGFPE during parsing

["Vakoc, Mark" <Mark_Vakoc jdedwards com>]

I am tracing down a similar problem in win32.  Evidently the various windows
platforms (not suprisingly) handle this differently.  I'll post a match when
I get it isolated.

   Initialization of Nan +Infinity and -Infinity in xpath.c:

-----------------------
double
xmlXPathDivideBy(double f, double fzero) {
    double ret;
#ifdef HAVE_SIGNAL
#ifdef SIGFPE
#ifdef SIG_IGN
    void (*sighandler)(int);
    sighandler = signal(SIGFPE, SIG_IGN);
#endif
#endif
#endif
    ret = f / fzero;
#ifdef HAVE_SIGNAL
#ifdef SIGFPE
#ifdef SIG_IGN
    signal(SIGFPE, sighandler);
#endif
#endif
#endif
    return(ret);
}
-----------------------


   The signal handler should be saved and restaured. This may
be platform specific.
