needs help to build gcc on Dec Alpha alphaev5-dec-osf5.0

[Philip Cheng]

I tried to build gcc 3.0.2 on my Dec Alpha alphaev5-dec-osf5.0
and I got the following error when I used "make bootstrap"
 
>checking for g++ that will successfully compile libstdc++-v3... configure: error: please upgrade to GCC 3.0 or above
>make[1]: *** [configure-target-libstdc++-v3] Error 1
>make: *** [bootstrap] Error 2
 
my g++ is v3.0 and I still could not build the libstdc++ library.
 
My config command is 
 
gcc-3.0.2/configure --enable-languages=c++,f77
 
I even tried setting  CC=cc  and CC=gcc -Wa, -oldas and it still failed.
Could somone please help?
 
Thanks

Philip
