+   This file defines typedefs for 8, 16, and 32 bit integers.  They are:
+   cit_int8_t  default 8-bit int
+   cit_int16_t default 16-bit int
+   cit_int32_t default 32-bit int
+   cit_int64_t default 64-bit int (not implemented yet)
+   cit_sint8_t signed 8-bit int
+   cit_sint16_t        signed 16-bit int
+   cit_sint32_t        signed 32-bit int
+   cit_sint64_t        signed 64-bit int (not implemented yet)
+   cit_uint8_t unsigned 8-bit int
+   cit_uint16_t        unsigned 16-bit int
+   cit_uint32_t        unsigned 32-bit int
+   cit_uint64_t        unsigned 64-bit int (not implemented yet)
+
+   The sizes are determined during the configure process; see the 
+   AC_CHECK_SIZEOF macros in configure.in.  In no way do we assume that any
+   given datatype is any particular width, e.g. we don't assume short is two
+   bytes; we check for it specifically.
+
+   This might seem excessively paranoid, but I've seen some WEIRD systems
+   and some bizarre compilers (Domain/OS for instance) in my time.
