You may want to study the source code of a well-written, modern C project like git: https://github.com/git/git
The fixed-size int finally got a permanent solution: #include <stdint.h>
If you are targeting autoconf/automake as your build system, that has a lot of built-in solutions to portability issues, like defining macros. It's not easy to learn, and I don't pretend to know it well, but when I'm compiling someone else's project, I'm always happy to see a configure script.
What I find annoying about libraries like glib is that they tend to impose their own style on your project by using their own typedef'ed types and such.
If you don't mind it, you can cobble together your own data structures from various open-source projects. Judy arrays are pretty fast, and you can use them in a variety of ways. Searching google for "c hash table" came up with a lot of excellent results, so try googling whatever data structure or algorithm you need, and chances are, you'll find something.

The gtk project's libglib is a pretty comprehensive library of C data structures. The Apache Portable Runtime serves a similar purpose: http://en.wikipedia.org/wiki/Apache_Portable_Runtime
