Comment 2 for bug 1570430

The xcb/xcb_bitops.h used to be part of xcb-util, but was dropped in version 0.4.0 from that package and moved to xcb-util-image. Unfortunately, the package fails to include the header, which can result in e.g. compilation failures.

It is also affected by Ubuntu 19.04 disco. Compilation for xcb failed. installing xcb_util_image package there were no xcb_bitop.h header file missing.
