* sqltypes.h
*
* This is the lowest level include in unixODBC. It defines
* the basic types required by unixODBC and is heavily based
* upon the MS include of the same name (it has to be for
* binary compatability between drivers developed under different
* packages).
*
* You can include this file directly, but it is almost always
* included indirectly, by including, for example sqlext.h
*
* This include makes no effort to be useful on any platforms other
* than Linux (with some exceptions for UNIX in general).
*
* !!!DO NOT CONTAMINATE THIS FILE WITH NON-Linux CODE!!!
