You could use one of the macros that are defined in 0.95 and not in
0.94, such as CL_INIT_DEFAULT.
#ifdef CL_INIT_DEFAULT
// ... code for 0.95+ API
#else
// .. code for <0.95 API
#endif
And if you use cl_init for 0.95+ API (as you should), then if there is a
mismatch between the headers and the library (for example 0.95 headers
and 0.94 libraries), then you'll get a linker error about cl_init not
being defined.
