Apologies for committing. I committed before I heard from you saying "No, don't", but apparently well after you had sent the message. My mail receiving must have been a bit off. :-/
Indeed, as I see from another message, you considered putting "part 1" as an early project and "part 2" as a stage 2 project, which was just fine by me. I am sorry I did not emphasize the standalone benefits of part 1 clearly enough in the project submission. They are sort of nebulous, but I think they're actually larger than the part 2 benefits: making gnattools a "host" directory, which it *should* be, gets us "correctness dividends" from not lying to the build system. By way of mitigation, the entire patch for the part 1 merge was submitted with information about testing and notification that I planned to commit it early in stage 1, in this message: http://gcc.gnu.org/ml/gcc-patches/2005-02/msg00926.html which came *after* my project submission and *before* the project scheduling list. -- This space intentionally left blank.
