So that it's included with the source files for 2.074.1.

@MartinNowak Thanks for this. Can I suggest also making a point release of the bootstrap compiler with this patch included, so that it's possible to build the whole of DMD etc. with a demonstrably free toolchain?

We're currently not setup to do additional point releases of older major versions, if it seems that urgent, you should be able to self-host the compiler once the point release binaries are out.

I looked into this a bit, to see where it's at. Two notes:

• The top-level license text that ships with dmd is outdated and contradicts the current licensing situation, that needs to be fixed.
• The file ddmd/readme.txt should note that the backend is also under the Boost license, otherwise someone may think it isn't since it isn't mentioned at all there now.
