%description devel
The %{name}-devel package contains libraries and header files for
developing applications that use %{name}.

If you are compiling a 32-bit program, no special compiler options are
needed.

If you are compiling a 64-bit program, you have to compile and link your
application with "cc -q64" or "gcc -maix64".
