Subject: egl: Drop xcb ifdefs by just requiring a version from this year.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b477384f4059cfda668c616c5655f2ee493cf6d1;p=mesa.git

egl: Drop xcb ifdefs by just requiring a version from this year.

glx and gallium's xcb_dri2 usage already require this version, so this is
nothing really new.
