Enum values from d.ts files cause exception when build with transpileOnly=true

I tried to speed up build process. And transpileOnly=true works amazing!
Until I use any enum value in my code.

Example:
Definition file: definitions.d.ts

declare module MyModule {
  export const enum MyEnum {
    EnumValue1 = 0,
    EnumValue2 = 1
  }
}

TS file: example.ts

/// <reference path="./definitions.d.ts" />
console.log(MyModule.MyEnum.EnumValue1);

In runtime I get error: "MyModule is not defined"
Is there any way to force ts-loader NOT to ignore some specific *.d.ts files when I use transpileOnly=true? (something like transpileOnlyExcept...)

Reproduce the failure from definitions.d.ts and example.ts with transpileOnly=true, then inspect how ts-loader handles referenced declaration files. Done means the example's enum access no longer fails at runtime with "MyModule is not defined", with the behavior covered by an appropriate loader test.
