Here is some ugly code for an addon module configuration script:

NGX_RAW_VERSION=`awk '/#define NGINX_VERSION/  {print $3}' \
         src/core/nginx.h`

NGX_VERSION_HEX=`${PYTHON} -c 'import sys; raw_version = sys.argv[1]; \
         v = map(int, raw_version[1:-1].split(".")); \
         print v[0] << 24 | v[1] << 16 | v[2] << 8' ${NGX_RAW_VERSION}`

have=NGX_VERSION_HEX value="$NGX_VERSION_HEX" . auto/define


It requires awk and Python.
