1) Provide an Open Source clean-room implementation of response_expand, the function the DMD frontend uses to parse response files. Unfortunately, it is under the copyright belongs (partly?) to Symantec, so Walter can't simply re-license it for use in GDC/LDC, where it is needed to provide DMD compatibility (gdmd/ldmd).

Hey David,

This looks like an interesting little project,
however I'm unsure on copyright matters etc etc.

I read the source code in:
https://github.com/D-Programming-Language/dmd/blob/master/src/root/response.c

Could you explain what needs to be done exactly ?
e.g.:
  How should such a clean room implementation look like ??
  Does the structure need to change ??
  Is it enough to rewrite the code in D ??
  Should the code be in C if so how much change ??

Well just some thoughts, but the code looks pretty straight forward..

Gr,
Danny Arends
