I mentioned compilation of PHP extensions, where this problem was observed.
A PHP extension may use some library, which provides its own config.h and
must use PHP API, which comes with another config.h, these can clash. Any
compilation, when different APIs are used, potentially may suffer from this
problem. Also the components may use different languages, C and C++.
