remove alloca from natMethod.cc

[Andreas Tobler]

Hi,

while digging with darwin and libgcj I struggle over a undefined
_alloca. A hint from Jeff S. showed me AG's patch for defineclass.cc
from last february.

I have now for natMethod.cc something similar.

Is this ok or completley wrong?

Thanks for feedback.

Built on darwin5.2.

Andreas

P.S. with the ar switches qc discussed parallel on java@gcc.gnu.org
