Configure correctly detects, there's no sdl installed but sdl support
is tried to be compiled nonetheless.
SDL shouldn't be compiled if only VNC is of interest.

Thanks for that report.  This should be fixed with this patch.

Ian.

commit 67f85e58d7622cdc9297bf6a216526fac28281ed
Author: Ian Jackson <ian.jackson@eu.citrix.com>

    Pass --disable-gfx-check to allow VNC-only builds.
    
    Qemu upstream inexplicably falls over during configuration if you will
    be forced to use VNC for graphics, as if that were somehow an
    unreasonable thing to do.  So hit that check on the head.
    
    Thanks to Christoph Egger for the report.

Sorry, no, this does not fix the problem.
configure already correctly detects, there's no SDL installed:

<snip>
-Werror enabled   no
SDL support       no        <----
OpenGL support
curses support    no
</snip>

The error is still the same:

It prints this complaint, yes.  The upstream configure script, for
reasons which are inexplicable, prints that error message _and then
exits successfully_.  So those errors are really a kind of warning.

I agree that they are inappropriate but I don't want to mess with the
upstream configure script any more than absolutely necessary as it is
something of a swamp.

Did you just run xen-setup ?  In my tree I see this:

mariner:qemu-iwj.git> ./xen-setup 
...
SDL support       no
...
The error log from compiling the libSDL test is: 
/tmp/qemu-conf-19939-21769-27099.c:1:17: error: SDL.h: No such file or directory
...
/tmp/qemu-conf-19939-21769-27099.c:3: error: for each function it appears in.)
mariner:qemu-iwj.git> echo $?
0
mariner:qemu-iwj.git

and a `make' succeeds.  Invokind xen-unstable build system works for
me as well.
