        ReportedBy: samsonluk@gmail.com


GCC version: 4.5.1 final
System type: i686 Ubuntu 10.04
Cross Toolchain: GNU C (Sourcery G++ Lite 2010q1-202) version 4.4.1
(arm-none-linux-gnueabi)compiled by GNU C version 4.3.2, GMP version 4.3.1,
MPFR version 2.4.2.
build systm type: i686-pc-linux-gnu
host system type: arm-none-linux-gnueabi
target system type: arm-none-linux-gnueabi
gcc source folder: /home/samson/src/gcc-4.5.1
gcc build folder: /home/samson/src/gccB451

gmp-5.0.1, mpc-0.8.2, mpfr-3.0.0 unpack to /home/samson/src/gcc-4.5.1 and
folder renamed gmp, mpc and mpfr respectively.

Options given when GCC was configured/built:
/home/samson/src/gcc-4.4.1/configure --prefix=/opt \
--host=arm-none-linux-gnueabi \
--target=arm-none-linux-gnueabi \
--disable-bootstrap \
--enable-languages=c,c++ \
--enable-threads=posix \
--disable-multilib \
--disable-libstdcxx-pch \
--enable-__cxa_atexit \
--disable-libgomp \
--without-ppl \
--without-cloog \
--enable-clocale=gnu
