Hi,

in addition to the stricter encoding checks that are a good thing and 
usually easy to fix, there are some cases where help would be appreciated:


Undefined control sequence errors in packages using dblatex.

And then there's libsynctex-dev, that changed the API from
   typedef struct __synctex_scanner_t _synctex_scanner_t;
   typedef _synctex_scanner_t *  synctex_scanner_t;
to
   typedef struct synctex_scanner_t synctex_scanner_s;
   typedef synctex_scanner_s * synctex_scanner_p;
breaking all reverse dependencies that were using synctex_scanner_t.


Thanks
Adrian
