** The SQLOLDCHAR macro may be used to maintain compatibility between
** version 1 applications and version 2 header files.  In version 1, many
** strings were declared as 'unsigned char'.  In keeping with the spirit
** of ANSI C, all character data, structure members and function
** parameters with string semantics have been changed to 'char' in version 2.
** This change may produce type conflicts with some compilers.  Adding
** -DSQLOLDCHAR to the compile command will cause the changed items to
** revert to their version 1 types.  Note that this should be used for
** compatibility purposes only.  New code should be written using plain
** 'char' where indicated in the documentation.
