/* In expermental (trunk) sources, MODULE_VERSION is a #define passed
in from the Makefile. It records the modification date of the
source directory -- that's the only way to stay sane. In release
sources, we (plan to) use the compiler's major.minor versioning.
While the format might not change between at minor versions, it
seems simplest to tie the two together. There's no concept of
inter-version compatibility. */
