Hi!
I am trying to build gcc 3.0 in fc4 with gcc 4.0.
After configure when i try to run the make command i get the following error message

make[1]: *** [cp/decl.o] Error 1
make[1]: Leaving directory `/root/applications/gcc-3.0-build/gcc'
make: *** [all-gcc] Error 2


can anybody guide me about the solution in easy steps...
Thanks in advance..

Please post more of the output.
The 5 or 10 lines preceding this would be very helpful.
