Bug#710322: clang-3.3: Support Headers not picked up cstddef and more

[Marc J. Driftmeyer]

Package: clang-3.3
Version: 1:3.3~svn179851-1~exp1
Severity: normal

Dear Maintainer,

Since so many packages have been pushed from experimental into Sid with GCC-4.7 and part of GCC-4.8 I decided to see how building LLVM/Clang from trunk works. It fails with assembly issues I'll file later using GCC-4.7 as the CC.

Now, I decide to install the LLVM-3.3/Clang-3.3 toolchain in its entirety to see how well it builds and this is what I get:

----------------

What is it with this latest transition in GCC-4.7.4 and GCC-4.8 that seems to throw this error each and every time I test it? Am I missing a package that can resolve the relocation of these header file paths or does Debian need to contact LLLVM/Clang and make sure those paths are included when building the infrastructure?

Sincerely,

Marc J. Driftmeyer
