           Summary: [GMCS] Expected compilation error when assembly A
                    references only assembly B, which has a class that
                    implements an interface in assembly C

gmcs allows compilation of an assembly, A, which references B and B references
assembly C. A declares a class that is in B.  B has a class that implements an
interface in assembly C.

To reproduce compile the attached files with these command line arguments:

bash-3.00$ gmcs -t:library LibOne.cs
bash-3.00$ gmcs -t:library LibTwo.cs -r:LibOne.dll
bash-3.00$ gmcs Program.cs -r:LibTwo.dll
Compilation succeeded - 1 warning(s)
bash-3.00$

The output from using csc is:

>csc -t:library LibOne.cs
