You're talking about two different problems here.  The "Bad system call"
is a result of either not having $CYGWIN set to contain the word "server",
or a result of Cygserver not running.

The failing assertion in Cygserver seems to be a problem of compiling
Cygserver with a g++ version which has some weird bug.  The latest
snapshot still has that problem, apparently.  I've just created a new
snapshot, which contains a Cygserver which should work fine.  At least
I tried it and it runs w/o assertion *and* I don't see the above
"MIT-SHM extension disabled due to lack of kernel support" message with
that Cygserver.
