+- Add conditional gcc6-c++ BuildRequires and #!BuildIgnore:
+  libgcc_s1 and also and pass -DCMAKE_C_COMPILER=gcc-6 and

-Subject: [PATCH] Disable GCC version check
-
-For openSUSE to compile with GCC 4.8, with -DENABLE_INDEXED_DATABASE=OFF
-and -DENABLE_DATABASE_PROCESS=OFF. It will probably work. The GCC 4.9
-requirement is because GCC 4.8 cannot handle some of the database
-process code.
