i am trying to build the gcc-frontend from source (version 2.8). Have already
built the LLVM part. Using gcc-4.2.2.
(configure and make command below). While building, get this error:

invalid option
exec: usage: exec [-cl] [-a name] file [redirection ...]

Unable to figure out where "-Q" is coming from.  Need help with this.

Configure command:
../configure --prefix=`pwd`/../install --program-prefix=llvm-
--enable-llvm=$LLVMOBJDIR --enable-languages=c,c++ --target=i686-pc-linux-gnu
--with-tune=generic --with-arch=pentium4

setenv LLVMOBJDIR /remote/vtgtools/llvm/llvm-2.8
