If the special comment //! is used within #if defined (..) regions, then the line following the comment is ignored. Since there are often function calls, the corresponding relations are missing in the XML and html documentation.

Here a short test program to reproduce the bug:

// main.c: Test file
//
#define APP_TYPE=BLH

void fctA () {};
void fctB () {};
void fctC () {};
void fctD () {};
void fctE () {};

/* FUNCTION ************************************************/
int main(int argc, char* argv[])
{
  // normal
  fctA ();	// correctly recognized
  
#if defined(APP_TYPE) && (APP_TYPE==BLH)  //! @crq _CRQ1129 
  //! @crq special comment
  fctB ();	// function call missing in doxygen documentation! BUG!!!
#endif  


#if defined(APP_TYPE) && (APP_TYPE==BLH)
//! @crq special comment with blank line

  fctC ();	// correctly recognized
#endif

#if defined(APP_TYPE) && (APP_TYPE==BLH)  //! @crq _CRQ1129 
  fctD ();	// function call missing in doxygen documentation! BUG!!!
#endif  			

//! @crq _CRQ1129 
fctE ();	// correctly recognized

  return 0;
