New issue 423 by s...@oax.com: Cannot compile protobuf example code on AIX
6.1
http://code.google.com/p/protobuf/issues/detail?id=423

What steps will reproduce the problem?
1. Install Google Protocol Buffers on AIX 6.1
2. export PKG_CONFIG_PATH=/PATH/protobuf-2.4.1
3. cd /PATH/protobuf-2.4.1/examples
4. make

What is the expected output? What do you see instead?
On Linux, the compilation of the protobuf example code succeeds. On AIX, I
get many errors. I've pasted the errors below that I get with the g++
compiler and the xlC_r compiler.

What version of the product are you using? On what operating system?
protobuf-2.4.1 on AIX 6.1

Please provide any additional information below.

Here are a sampling of the compilation errors I'm getting:

Errors with g++ compiler

There are about 100 of these errors.
