%description
The GNU Compiler Collection (GCC) provides standard conforming and
highly portable compilers for the ISO C and ISO C++ languages. This
is the OpenPKG GCC Bootstrap package which is based on GCC 4.7, the
last major version which can be built with just a system C compiler.
It is required to be built and installed for building the latest GCC
package in case the system compiler does not support C++. As it has
just this single purpose, all package options were removed and the
minimum GCC extend is compiled.
