[LLVMdev] LLVM GCC - 4.0 from svn build error

[Prem Mallappa]

Hi All,
it bails out with unable to detect exception model error

I checked with my configure
$LLVM_GCC_SRC/configure --prefix=$LLVM_GCC_INST
--program-prefix=llvm-             -enable-llvm=$LLVM_BUILD
--enable-languages=c,c++ --enable-checking

I haven't enabled objc but it seems to get error whille configuring objc.
any idea how to get rid of this
