Question

Google officially provides a C++ implementation of Google Protocol buffers,
but I’m looking for a C implementation.

I will not be using it myself, but my hope is that I can use this tool to generate
C code for our Google Protocol Buffer definitions which I can then hand of to the C developers.

I’m not looking for any RPC functionality, simply encoding and decoding of Google Protocol Buffer messages.

Use protobuf-c (now at Github as protobuf-c).

From their official site:

This package provides a code generator and runtime libraries to use
Protocol Buffers from pure C (not C++).

It uses a modified version of protoc called protoc-c.
