[LLVMdev] Problem when build llvm-gcc using llvm-gcc4.2-2.5.source.tar.gz

[Heyu Zhu]

Hi,

The gcc version in my system is 3.4.6
During make display error message and stop

 cc1plus:error: unrecognzied command line option -Wno-variadic-macros

Must i update gcc to version 4.2.0 or above to resolve the problem?

Thanks
