/* The compiler calling convention varies depending on the target
 * processor family; therefore, there often needs to be separate
 * prototypes depending on which compiler is being used.
 *
 * MPLAB-C18 provides the __18CXX environment variable which will
 * allow us to know that we're compiling for an 18c part. Future
 * versions of MPLAB-C17 will have a corresponding __17CXX environment
 * variable, but as of v2.30.03, it does not.
 *
 * Since the only two Microchip compilers currently available are
 * MPLAB-C17 and MPLAB-C18, the presence or absence of __18CXX
 * is sufficient to determine the target platform.
