Summary 0006682: Quote vs bracket include behaviour not correct
Description Trying to parse a project include file everything.h, layout is like this:

everything.h:

#include "string.h"

string.h:

#include <string>

class StringXXX {... };

The test case is attached.

g++ (4.2) compiles this fine, but gccxml gives errors or, in a larger project tree, skips the string.h header altogether.
Steps To Reproduce
Additional Information gccxml errors:

 This has nothing to do with quotes versus angle brackets. It's because you have a header "string.h" that duplicates a standard header name. In gccxml the gcc preprocessor is patched to use a "wrapper" include path that overrides standard headers. This allows standard headers from simulated compilers to be copied and patched to parse with the gcc parser. The problem is that this mechanism is conflicting with your header name.

In general I think having project headers that duplicate system header names is a bad idea. Yes, it can be made to work by depending on the "" v. <> style include. However I've seen (cross-) compilers that do not implement it correctly. It is also confusing to others reading the code.

Nevertheless gccxml may be able to be fixed to handle this case. I'm not sure when I can get to it though. For now, if renaming the header is a possibility I suggest doing so to work around this problem.

 I've fixed issue 0009468 which is the same as this except that the test case does not use a system header name. There was a subtle interaction problem between a gcc optimization and a gccxml change that was made before the optimization was merged. I think it may fix this problem too. Please re-open if it does not.
