You can either use M4 macros
m4_define([SKMAJOR], [42])
or initialize the variables after AC_INIT. It's out of necessity that
shell lines prior to AC_INIT are ignored: the sanitize shell startup
code to put some of the shells in a sane mode of operation needs to come
early in the script.
This is an Autoconf issue, by the way.
