Playing around with CFLAGS="-Wall -Werror", I hit the following warning, from
the -pedantic flag set by configure.ac, promoted to an error:

libtool: compile:  gcc -DHAVE_CONFIG_H -I. -Wall -pedantic -Wpointer-arith
-Wstrict-prototypes -Wmissing-declarations -Wnested-externs -Wall -Werror -MT
dri2.lo -MD -MP -MF .deps/dri2.Tpo -c dri2.c  -fPIC -DPIC -o .libs/dri2.o
cc1: warnings being treated as errors
dri2.c: In function ‘xcb_dri2_connect_alignment_pad’:
dri2.c:332: error: invalid application of ‘sizeof’ to a void type
