There was an issue recently in screen-share.c where config.h was not being included, resulting in the wrong definition for off_t being used on 32 bit systems. I checked and I don't think this problem is happening elsewhere, but to help avoid this sort of problem in the future, I went through and made sure that config.h is included first whenever system headers are included. The config.h header should be included before any system headers, failing to do this can result in the wrong type sizes being defined on certain systems, e.g. off_t from sys/types.h Signed-off-by: Andrew Wedgbury <andrew.wedgbury@realvnc.com>
