Hi,

I tried to compile the following program:

#include <complex.h>
int main(void)
{
        double_complex a(1.0, 0.0),b;
        b=a+a;
        printf("b=%f  %f\n",real(b),imag(b)); 
        return 0;
}


It fails during the link stage with the error:
/var/tmp/cc0255091.o: Undefined symbol `___pl__FRCt7complex1ZdT0' referenced from text segment

However, when I replaced b=a+a with b=a-a everything worked.
At least, I found a missing definition in /usr/src/gnu/lib/libstdc++/Makefile:
We find SUBCC SUBCF SUBFC defined but only ADDCF ADDFC.
After applying the following path everything worked. Is this correct or
is there something different wrong (This is the first time I had something
to do with g++ :-))?

If it is correct, could someone bring it into the STABLE-tree, please?

Thanks,
	Andre
