gcc-4.6.2 build problem related to xgcc not liking '-V' option on i686-pc-linux-gnu

["Sinkler, Wharton" <Wharton dot Sinkler at uop dot com>]

I have been trying unsuccessfully to install gcc-4.6.2, on a Redhat Linux VM.? The configure step seems to work fine.? I'm using the following configure options (installing 4.6.2 from a 'gcc_build' directory as suggested on the website; I already installed the required dependencies under /usr/local as indicated):

../gcc-4.6.2/configure --with-gmp=/usr/local --with-mpfr=/usr/local --with-mpc=/usr/local --with-ppl=/usr/local --with-cloog=/usr/local \
???? LDFLAGS="-L/usr/local/lib -Xlinker -R/usr/local/lib" CONFIG_SHELL=/bin/bash -enable-languages=c,c++,fortran

Under 'make' I am getting the following error:

checking for suffix of object files... configure: error: in `/home/E341484/gnu-install/gcc_build/i686-pc-linux-gnu/libgcc':
configure: error: cannot compute suffix of object files: cannot compile
See `config.log' for more details.

I found more detail on the make failure in the file ./i686-pc-linux-gnu/libgcc/config.log, which shows an error occurring at this statement:

configure:3028: /home/E341484/gnu-install/gcc_build/./gcc/xgcc -B/home/E341484/gnu-install/gcc_build/./gcc/ -B/usr/local/i686-pc-linux-gnu/bin/ -B/usr/local/i686-pc-linux-gnu/lib/ -isystem /usr/local/i686-pc-linux-gnu/include -isystem /usr/local/i686-pc-linux-gnu/sys-include??? -V >&5
xgcc: error: unrecognized option '-V'
xgcc: fatal error: no input files
compilation terminated.

I think this is really the cause of the problem.? I think the upper-case V might be an error, and should be a lower case '-v'.? If I run this command with the 'V' changed to 'v', it executes successfully, returning an assortment of information, including info on the gcc version (and no error).? 

Is this a bug in the Makefile?? Is the upper-case '-V' supposed to be a '-v', or am I missing something?? If the 'V' should be a 'v', any suggestions how to fix this in the Makefile?  ? 

Thanks!?
