From 2c570e76d4c627a0b0417cfa0d0f2e787a6d629d Mon Sep 17 00:00:00 2001 From: Jan Engelhardt Date: Thu, 5 Jun 2008 19:54:48 +0200 Subject: build: check for missing feature files linux/dccp.h is unlikely to be installed before 2.6.18 (which was when headers_install was introduced), and does not exist at all before 2.6.14. Add a compile-time check to skip compilation of libxt_dccp in case this was detected.
