Note the attempt to make all basic types have 4 letters.
This improves readibility and standardizes the code.
Likewise, all complex types are at least 4 letters.
Thus, almost every three letter word is a legal variable.
But beware of certain reserved words ('for' and 'if' and 'do').
Note that the type used in structures for bit flags should be uint.
As long as these bit flags are sequential, they will be space smart.
Note that on some machines, apparently "signed char" is illegal.
It must be true that char/byte takes exactly 1 byte
It must be true that sind/uind takes exactly 2 bytes
It must be true that sbig/ubig takes exactly 4 bytes
On Sparc's, a sint takes 4 bytes (2 is legal)
On Sparc's, a uint takes 4 bytes (2 is legal)
On Sparc's, a long takes 4 bytes (8 is legal)
On Sparc's, a huge takes 4 bytes (8 is legal)
On Sparc's, a vptr takes 4 bytes (8 is legal)
On Sparc's, a real takes 8 bytes (4 is legal)
Note that some files have already been included by "h-include.h"
These include <stdio.h> and <sys/types>, which define some types
In particular, uint is defined so we do not have to define it
Also, see <limits.h> for min/max values for sind, uind, long, huge
(SHRT_MIN, SHRT_MAX, USHRT_MAX, LONG_MIN, LONG_MAX, ULONG_MAX)
These limits should be verified and coded into "h-constant.h".
