I have VERISRELEASE to mark that it is a developement version, I am not sure we
need the beta number. I would prefer to do it like httpd.
But will this be ok?
mod_jk/1.2.0-beta-01 (for the first beta)
mod_jk/1.2.0 (for the release version).

What about:
#ifdef RELEASE
#define JK_VERSION JK_MKVER(1, 2, 0, 99)
#else
#define JK_VERSION JK_MKVER(1, 2, 0, JK_BETA)

Hex is a copy + paste from Linux sources. Dec is more easy? - No problem - But I
like to  write 0x010200 and 0x110200 it is easy to see than 10200 and 110200.
