Dear Bernd Kuhls,
I have tested your patch and indeed fixes the problem. But I have some
comments regarding your commit log.

What I see at the line 1641 of that URL is this:
--------------
if test "x$WAYLAND_SCANNER" = x; then
AC_MSG_ERROR([wayland-scanner is needed to compile the wayland egl
platform])
fi
;;

I think you probably mean line #1650, which has:
--------------
drm)
test "x$enable_gbm" = "xno" &&
AC_MSG_ERROR([EGL platform drm needs gbm])
test "x$have_libdrm" != xyes &&
AC_MSG_ERROR([EGL platform drm requires libdrm >= $LIBDRM_REQUIRED])

Due to the spaces at the beginning of those lines, some of them are
longer than 72 characters. Perhaps you could remove those unnecessary
spaces.

Vincent.
