The following commands can be used to build SDL for RISC OS using autoconf:
./configure --host=arm-unknown-riscos --prefix=$GCCSDK_INSTALL_ENV --disable-gcc-atomics
./configure --host=arm-unknown-riscos --prefix=$GCCSDK_INSTALL_ENV
make
make install
The following commands can be used to build SDL for RISC OS using CMake:

When using GCCSDK 4.7.4 release 6 or earlier versions, the builtin atomic functions are broken, meaning it's currently necessary to compile with `--disable-gcc-atomics` using autotools or `-DSDL_GCC_ATOMICS=OFF` using CMake. Newer versions of GCCSDK don't have this problem.
