The __SRCVERSION macro is defined in the header file sys/srcversion.h and causes the string given with the macro to be included into the resulting binary as a special section. This way, the origin and version of all source files used to build an executable can be extracted from the binary, to allow a precise reference/rebuild if necessary.
