I did not see this before 10.3.9.  The problem is that math.h was not  
updated
for the library changes which went into 10.3.9.  There are three ways  
around this,
either downgrade to 10.3.8, fix math.h somehow, or upgrade to Tiger.  I  
have taken
the first approach, well I never updated in the first place.

This is not a bug in GCC or libstdc++ but how Apple handled the update  
which in my
mind was wrong.

Thanks,
