[Patch] (3.0.4pre, arm) : get libstdc++ working

[jeroen dobbelaere]

Hi,

following patch fixes the behavior of g++ for arm.
It is against the gcc-3_0-branch.


The difference can be seen by comparing following testresults :

before :

   <http://gcc.gnu.org/ml/gcc-testresults/2002-02/msg00075.html>

after :

   <http://gcc.gnu.org/ml/gcc-testresults/2002-02/msg00102.html>

This should also resolve the problem of compiling a
simple 'hello world' c++ program.

IMHO, this patch is definitely needed for gcc-3.0.4 !

Greetings,
