decimal.cs

Compile the attached file with:

> mcs decimal.cs /target:library /nostdlib

an error is shown:

> decimal.cs(53,13): error CS0188: The `this' object cannot be used before all of its fields are assigned to
> Compilation failed: 1 error(s), 0 warnings

The file compiles fine with csc.exe on Windows.

Note: this code is a reduced form of the Decimal class in MS referencesource. When Miguel imported that code into Mono he had to work around the mcs constructor bug in https://github.com/mono/referencesource/commit/9c6e5e2ee332d23c8d07e311c234337205d22642.
