Looks like what I've been looking for--a ready-made parser for C that's made for exposing the structure of the source code for analysis

An interesting summary of problems with C89 (and C99) type qualifiers. 'noalias' sounds very, very similar to C99's 'restrict', but it's possible that a subtle difference in the semantics invalidates most of Ritchie's criticism in this page.

" ... GCC 4.2 and later includes support for the proposed ISO C extensions for decimal floating point ... " Comprehensive overview of decimal arithmetic, fixed and floating point

Illustrates a generic interface for a hash table library in C. The syntax used is more elegant than anything I've seen like it.

A treasure trove of efficient bit manipulation functions

" ... I slowly awoke from a dream, or more accurately, a mild nightmare. My C code also worked, except it was faster. It was more concise, which in turn made it easier to maintain. It was…better. So why was I bothering with all this object-oriented nonsense?

Since rediscovering C, I have felt annoyed that I had bought into object-oriented programming. It is unsurprising, as both industy and academia tirelessly promoted objects, and still do today. The constant and pervasive assault irks me, though I am cheered whenever I read articles from dissenters. It’s time I added my voice. ... "

Google-sponsored C replacement from what looks like most of the entire original Bell Labs team. Garbage-collected, with facilities for parallelism and a typing system that mostly resembles Python's (although presumably not evaluated at runtime). Some measures to reduce the verbosity of C, but not a lot.

" ... Have you ever wondered what SO_LINGER is actually for? What TIME_WAIT does? What's the difference between FIN and RST, anyway? ... "

" ... I have spent many years working on the FreeBSD kernel, and only rarely did I venture into userland programming, but when I had occation to do so, I invariably found that people programmed like it was still 1975 ... "

" ... In other words, instead of calling a function directly, the dyncall library provides a mechanism to push the function parameters manually and to issue the call afterwards ... "

" ... Memory blocks allocated through halloc can be organized into a hierarchy of parent-child relationships. These relationships are taken into an account when memory block is being freed - disposing the block automatically frees all its children in a recursive way ... "
