Re: upgrading gcc-4.4.0 to gcc-4.7.0:configure: error: cannot compute suffix of object files: cannot compile

["damodar.sonone" <dsonone@xxxxxxxxx>]

Hello,
sorry, the previous log was from "libcpp folder" under gcc-build & below is
the error log from config.log file from libgcc folder.

-------------------------------
Config.log in libgcc folder:
-------------------------------
<snip1>
xgcc: error: unrecognized command line option '-V'
xgcc: fatal error: no input files
compilation terminated.
configure:3418: $? = 1
<snip1>
<snip2>
conftest.c: In function 'main':
conftest.c:16:1: internal compiler error: in reg_save_code, at
caller-save.c:158
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
configure:3437: $? = 1
configure:3625: checking for suffix of object files
<snip2>

Please suggest what is missing.

There are several "errors" in config.log file, most of which I observed even
when the GCC-4.4.0 build successfully. I do not know how to resolve all of
these errors.
