   I was having a look through the header files for a SAT-solver that I   
   needed to work out how to use, and which for some reason seemed to be   
   using a lot of the C versions of the headers ( instead of   
    for instance) alongside C++ headers such as .   
      
   Which is how I encountered this:   
      
   #include    
   #include    
   #include    
      
   Does anyone know of any reason why someone would want to #include both   
   stdio.h and cstdio in the same file? More importantly, are there any   
   potential pitfalls to doing this? If there are, can I just fix them by   
   commenting out the line with stdio.h?   
      
   A slightly less important question as well - does anyone know of any   
   reason not to change  to  in the above? I can easily   
   go through the file putting std:: before function names and the like.   
      
   Many thanks,
