%description
This is a Cross Compiling version of GNU GCC, which can be used to
compile for the %{target} platform, instead of for the
native %{_arch} platform.
This package is based on the CodeSourcery %{cs_date}-%{cs_rel} release,
which includes improved ARM target support compared to the corresponding
GNU GCC release.

%description c++
This package contains the Cross Compiling version of g++, which can be used to
compile c++ code for the %{target} platform, instead of for the native
