--- Comment #2 from Ilya <mirraz1 at rambler dot ru> --- (In reply to Manuel López-Ibáñez from comment #1) > Not a problem. See: > > http://gcc.gnu.org/wiki/FAQ#stage1warnings > GCC is built in stages. The first stage uses the system compiler, which may > have bugs or not handle special conversion type characters handled by the GCC > version being built (this particular warning). Therefore, warnings produced > by the system compiler are often wrong. Please, do not report them. The system compiler for the first stage was also gcc-4.7.3
