help needed with recent svn and mono

[delete123]

hi!

i tried to compile today's svn with mono versions 1.2.6 and 1.9.

in "Server" source, i type:

gmcs -recurse:*.cs -unsafe+

output is:

./Main.cs(451,37): warning CS0219: The variable `ms' is assigned but its value is never used
./Map.cs(1797,33): warning CS0219: The variable `start' is assigned but its value is never used
./Mobile.cs(8756,32): warning CS0219: The variable `oldRegion' is assigned but its value is never used

Compilation failed: 1 error(s), 4 warnings
