-** @author	Warren R. Carithers
-**
-** Print byte offsets for fields in various structures.
-**
-** This program exists to simplify life.  If/when fields in a structure
-** are changed, this can be modified, recompiled and executed to come up with
-** byte offsets for use in accessing structure fields from assembly language.
-** It makes use of the C 'offsetof' macro (defined since C89).
-**
-** IMPORTANT NOTE:  compiling this on a 64-bit architecture will yield
-** incorrect results by default, as 64-bit GCC versions most often use
-** the LP64 model (longs and pointers are 64 bits).  Add the "-mx32"
-** option to the compiler (compile for x86_64, but use 32-bit sizes),
-** and make sure you have the 'libc6-dev-i386' package installed (for
-** Ubuntu systems).
-**
-** WATCH FOR clashes with standard system functions; compile with the
-** "-fno-builtin" option to avoid warnings about clashes with builtin
-** function declarations.
-**
-** Writes to stdout. Output contains information about type sizes and
-** byte offsets for fields within structures.  If invoked with the -h
-** option, the output takes the form of a standard C header file; 
-** otherwise, the information is printed in ordinary text form.
-**
-** If compiled with the CREATE_HEADER_FILE macro defined, when invoked
-** with the -h option, writes the data directly into a file named
-** "offsets.h".
