the "g++.dg/expr/anew4.C" test case fails if compiled with sx-g++ #130

The "g++.dg/expr/anew4.C" test case, which tests the "new" array operator,
with zero-initialization and a variable sized array fails if compiled with
sx-g++.

The problem is in the "p[i].x" value. The test expects 0, whereas our value
is -nan.

Humm, funny, this test also fails if compiled with the i386 gcc compiler. 
Apparently,
if program is compiled with the default switches, the array constructor doesn't
initialize the array elements to 0 in both cases, SX and i386.

As it turns out the test above is expected to fail (now I know what the XFAIL 
tag
means... ;) )

According to the gcc bugtracker (see the link below), the "new" constructor for
arrays shouldn't initialize the elements to 0:
