The _autoconf_table.c is autogenerated file and is very simple it should compiled by any compiler. Maybe it is awk release issue? Is it possible that downgrading gcc you are downgrading the awk too? Can you post the (auto-generated) _autoconf_table.c file which fails to compile?
This bug should be solved in c-icap-0.6.3 release. If you still has the issue please report.
