GPERF generates perfect hash functions for sets of key words.
A perfect hash function is simply:
A hash function and a data structure that allows
recognition of a key word in a set of words using
exactly 1 probe into the data structure.
Output from the GPERF program is used to recognize reserved words in
the GNU C, GNU C++, and GNU Pascal compilers, as well as with the GNU
indent program.

Gperf was bundled with libg++. Now that libg++ has been removed from
the main tree, some people may find gperf useful.
