a few questions so far:
1) where does "cors_enable=true get set  - tried to do sudo ./configure 
--cors_enable....  that didn't work
2) ini file ?  is that a windows thing ?  - also would be helpful to 
have an example of that
3) using autoconf gave the following:
configure.ac:22: error: possibly undefined macro: AM_CONFIG_HEADER
       If this token and others are legitimate, please use m4_pattern_allow.
       See the Autoconf documentation.
