asynchronous-exceptions handling

[Rabin Shahav (r53653)]

// The -fasynchronous-exceptions flags is not
working !
// here is a sample of an exception thrown from a
signal
// handler. This exception terminates the program
although
// it is a wrapped with "catch" statement.
// Note: this bug doesn't occur on gcc-2.7.x!!!
// compile with g++ -v -g  -fasynchronous-exceptions
a.cc
// on sun ultra1 running solaris 5.7
