I tracked down the document which changed the way variables are handled in for loops for C99, it was the same document that allowed mixing code and declarations but the editor's report made it seem like the features came from different papers. This is an extension we backported to C89 but it's sufficiently distinct in the tracking page so I've added it explicitly to the backported features documentation.
C language Family Front-end
Welcome to Clang.
This is a compiler front-end for the C family of languages (C, C++ and Objective-C) which is built as part of the LLVM compiler infrastructure project.
Unlike many other compiler frontends, Clang is useful for a number of things beyond just compiling code: we intend for Clang to be host to a number of different source-level tools. One example of this is the Clang Static Analyzer.
If you're interested in more (including how to build Clang) it is best to read the relevant websites. Here are some pointers:
