Thanks for the info, attached is a new version of hw/vnc/init.c that has
mouse wheel support (copied from hw/xquartz/darwin.c).
Oh, and this version actually compiles with the current git tree.
BTW, my built Xvnc does not yet work correctly, I am currently
trying to debug this problem (the "=+=" msg is my debug printf) :
