* GDL VERSION NUMBERS
*
* We currently maintain two types of version information:
*
* GDL version
* This varies with major redefinitions of the user API. It comprises:
* - a 4-bit major version number
* - a 16-bit minor version number, and
* - a 4-bit hotfix number (which will normally be 0).
* These numbers are determined by the #define's below. Hotfix numbers
* should be incremented for each hotfix release, and should be reset to 0
* when one of the other numbers is rolled.
*
* An application can retrieve the version number via the
* gdl_get_driver_info() API.
*
* Header version
* It is possible for internal changes to be made to shared header files
* resulting in incompatibility among the following components if they
* are built with different versions of the header files:
* - user applications
* - libgdl.so
* - gdl_mm.ko
* - gdl_server
*
* The header version number is composed of 16-bit major and minor numbers
* assigned via the #define's below. THE MINOR NUMBER SHOULD BE ROLLED
* whenever a backward-compatible change is made. THE MAJOR NUMBER SHOULD
* BE ROLLED whenever changes are made that are incompatible with previous
* versions of the user library.
*
* Compatibility is checked in gdl_init().
*
* The header version is also returned via the gdl_get_driver() API.
