Do you have any news on that, Anish?
I just tried to disable the mmap calls that have been causing troubles,
by means of the patch below, which leads to a different error -- Wine is
rapidly deteriorating on FreeBSD, we really need to get something working
soon, or it'll be dead in the water forever. :-(

If I try to run the current (= October) version of Wine with the patch
below, on FreeBSD 4.10, I get: assertion "libc_sigaction" failed: file
"kthread.c", line 943.
