Mostly, because I want to keep building and installing Clang simple. When I
wrote this, if someone checked out the Clang codebase following the
instructions on the website, and built it using CMake, it would fail to
build. The default compiler on most systems is GCC still, and so it seems
unreasonable to abandon support for it...

FWIW, I'll immediately become OK with requiring a bootstrap when the build
system does it for us, so that users can check out the code, build and
install it in "one go". I'm mostly concerned with keeping the development
process simple, not with the particulars of one host compiler vs. the other.


As a final note, it turned out to be very easy to fix this. I should have
updated this thread. I think everything will work as of r165863.
