[Mono-dev] Recent C# compiler changes

[Justin Bailey]

I'm having trouble building today's tarball (20110204). 'mod' fails to build:

  make[8]: Entering directory `/xxx/home/baileyj/mono-20110204/mcs/tools/mod'
  MCS     [net_4_0] mod.exe
  error CS0006: Metadata file `./../../class/lib/net_2_0/monodoc.dll'
could not be found
  Compilation failed: 1 error(s), 0 warnings

Could it be related to the new SDK flag? monodoc.dll does not show up
under any directory after running make.
