+ Issue 09/09/2006
+
+ The unsigned integer types defined here are of the form uint_<nn>t where
+ <nn> is the length of the type; for example, the unsigned 32-bit type is
+ 'uint_32t'.  These are NOT the same as the 'C99 integer types' that are
+ defined in the inttypes.h and stdint.h headers since attempts to use these
+ types have shown that support for them is still highly variable.  However,
+ since the latter are of the form uint<nn>_t, a regular expression search
+ and replace (in VC++ search on 'uint_{:z}t' and replace with 'uint\1_t')
+ can be used to convert the types used here to the C99 standard types.
