I ran into this linking-problem after I reinstalled my system
and it ended in Patches, that display additional Packaged with
"./configure --verbose".

"-lSM" is added to "configure" by m4/autoconf, when checking for
"libICE" and the check for "libICE" is introducd by "AC_PATH_XTRA"
in our "configure.ac".

I spotted that on #winehackers but had no time to add a bug-report
to autoconf or m4 yet.

We can add a check for "libSM" to work-around this autoconf/m4 - bug,
but IMHO, autoconf is the correct place for the fix.
