It's not that easy for code that wants to print such integers, as %ld doesn't 
suffice on MinGW and older POSIXish libraries don't support %jd etc. Perhaps 
once Gnulib assumes C99-or-later libraries, and once somebody goes through all 
the Gnulib code and checks it. In the meantime we should probably leave 
something like that sentence in there, although we should warn people about the 
MSVC issues. I installed the attached to try to do that, and to try to clarify 
the issues about C89 vs C99 vs C11 that were in Paul's question.
