--- Comment #1 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- Cf what I said in <https://gcc.gnu.org/ml/gcc/2015-10/msg00189.html>: I think we should clearly update the documentation to reflect reality regarding source file encoding, and leave it strictly for wrappers such as "c99" to specify -finput-charset= options rather than leaving open the possibility that GCC's own default might change in future.
