+/**
+ * check_type - routines for compile time type checking
+ *
+ * C has fairly weak typing: ints get automatically converted to longs, signed
+ * to unsigned, etc.  There are some cases where this is best avoided, and
+ * these macros provide methods for evoking warnings (or build errors) when
+ * a precise type isn't used.
+ *
+ * On compilers which don't support typeof() these routines are less effective,
+ * since they have to use sizeof() which can only distiguish between types of
+ * different size.
