Well, "%a" has always been a format character for an automatically
allocated string ("The GNU C Library Reference Manual", Vol. 1,
Chapter 12.14.6, "Dynamically Allocating String Conversions").
Why would that change with -std=c++11?
and of course, warnings about
invalid suffix on literal; C++11 requires a space between literal and
string macro
in dvbsubtitle.c remux.c
I've already adopted that for the next version.
