- use standard headers
- declare functions before calling them
- use c89 function declarations
- give functions return types, including sometimes "void"
- silence clang and gcc warnings about assignments inside conditionals
- silence clang warnings about braces
- silence gcc warnings about unused/uninitialized variables
- fix insecure-temporary-files
- use snprintf() instead of sprintf()
- call free() correctly
- call qsort() correctly
- pass gcc -Wall -Werror (with gcc 4.5)
