[4.0.0] "make check-g++" fails linking tests on powerpc-apple-darwin7.9.0

[Douglas Gregor]

Running "make check-g++" for GCC 4.0.0 fails any tests that need to  
link on powerpc-apple-darwin7.9.0, with error messages such as:

/usr/bin/ld: warning suggest use of -bind_at_load, as lazy binding may  
result in
  errors or different symbols being used
symbol _tanl used from dynamic library  
/Volumes/scratch/dgregor/gcc-concepts-con
fig/powerpc-apple-darwin7.9.0/./libstdc++-v3/src/.libs/ 
libstdc++.dylib(single mo
dule) not from earlier dynamic library  
/usr/lib/libSystem.B.dylib(ld64.o)

We've seen these before on powerpc-apple-darwin7.x.0 (x < 9), but they  
were always fixed by updating cctools to something > cctools-495. I'm  
using cctools-576. The same problem occurs with mainline GCC (4.1.0).

Does anyone know how this can be fixed?

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,
