From 834193484439acd6056a891e9b2df5992a370088 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Tue, 22 Mar 2011 16:36:13 +0100 Subject: include: reorganize headers file to include/osmocom/[gsm|core] This patch moves all GSM-specific definitions to include/osmocom/gsm. Moreover, the headers in include/osmocore/ have been moved to include/osmocom/core. This has been proposed by Harald Welte and Sylvain Munaunt. Tested with `make distcheck'.
