Created attachment 179989 [details]
contains configuration file (config), source files (one.cxx and two.cxx), generated result dir (doc_gen)

Hi,

Actually, I am trying to document lex/yacc files. For them I generate the cxx files and use them with doxygen. The problem is that since there are multiple lex files and each produce #define with same names. Which causes wrong behavior for the conditional compilation.

Have attached a tar ball containing two cxx files which have the same content. The pre-processing for both of them is different. 

I think the problem is that g_fileDefineDict is not cleared before each processing.
