Eclipse CDT indexer adding unwanted quotes to symbol

In a project, I am using separate header files to specify parameters for separate configurations. For example, config1.h and config2.h. I have created separate build configurations in Eclipse for each configuration and added symbol PARAM_H_FILE assigned either PARAM_H_FILE=config1.h or PARAM_H_FILE=config2.h in Eclipse as a defined symbol for the respective build configuration. In order to include this file, I have added the following lines to a common header file in the project:

#define QT(filename)    #filename    //!< Convert filename to string
#define QUOTE(filename) QT(filename) //!< Expand filename string

// Include header file.
#include QUOTE(PARAM_H_FILE) // Include vehicle definitions

The compiler expands this to #include "config1.h" or include "config2.h" as desired and compiles with no errors or warnings. However, the Eclipse CDT indexer expands this to #include "\"config1.h\"" or #include "\"config1.h\"", resulting in detected errors any time the macros defined in config1.h or config2.h are referenced in the code.

Also, I found that if I replace the above code with the following, then Eclipse does not detect any errors, but the project compiles with errors:

#include QUOTE(PARAM_H_FILE) // Include vehicle definitions

Is there any way to specify the header file name as a defined symbol in Eclipse that will prevent the indexer from identifying errors and allow the project to build.

I have tried formatting the symbol definition as: PARAM_H_FILE=config1.h, PARAM_H_FILE='config1.h', PARAM_H_FILE='"config1.h"' and PARAM_H_FILE="config1.h" and nothing seems to work.

As a point of reference, I am using is MinGW.org GCC-8.2.0-5 in Windows and Eclipse IDE for C/C++ Developers, Version: 2019-06 (4.12.0).

After investigating further, I found that this was being caused by an &quot; added before and after the symbol assigned value in the .cproject XML file. This may have been added by an older version of Eclipse. In Eclipse 2019-06 (4.12.0), the quotation mark indicated by &quot; is not visible in the Project Properties window.

For example, the XML file may read:

<listOptionValue builtIn="false" value="&quot;PARAM_H_FILE=config.h&quot;"/>,

But the Project Properties reads:

VC_PARAM_H_FILE=config.h instead of VC_PARAM_H_FILE="config.h".

The easiest way to remove &quot; manually from the .cproject XML file.
