[cp-patches] [patch] native/fdlim unitialized fixes

[Andreas Tobler]

Hello,

on request of Michael I put the diff together I applied to libgcj.
Here against classpath cvs. I built it but I could not test classpath so 
far. I tested it on libgcj.

Andreas

P.S, if accepted could someone please commit ?

        * java/lang/dtoa.c (_dtoa_r): Initialize variables ilim, ilim1 and
        spec_case. Initialize pointer mlo.

        * java/lang/strtod.c (_strtod_r): Initialize pointers bb, bd, 
ds and
        delta.

        * java/lang/e_asin.c (__ieee754_asin): Initialize variable t.

        * java/lang/e_exp.c (__ieee754_exp): Initialize variables hi, lo
        and k.

        * java/lang/e_rem_pio2.c (__ieee754_rem_pio2): Initialize
        uninitialized variable z.
