* without it forcing a recompile on something ccache would otherwise not
* have to rebuild...this file's checksum changes every time you build it
* due to the __DATE__ and __TIME__ macros.
*
* The makefile will rebuild this file everytime it relinks an executable
* so that we'll always have a unique build string.
*
* APPNAME and APPREV need to be predefined in the build system.
* The rest are supposed to be supplied by the compiler.
