config.h doesn't have include guards, so including it twice is bad. We deal with this by checking for PACKAGE_NAME, but only in some places. Once we start using gnulib, we will need to include config.h before any gnulib-generated headers. This is problematic if we include it transitively through our own private headers. In order to set a clear rule about inclusion of config.h, it is now included in every .c file as first header, but not in any header. This will definitely avoid double-inclusion and satisfy the condition that it has to be included before gnulib headers. It comes at the price of adding some redundancy, but there is no clean way to avoid this. Signed-off-by: Ulf Hermann <ulf.hermann@qt.io>
