--- Comment #6 from Bernd Edlinger <bernd.edlinger at hotmail dot de> ---
also the -fno-extended-identifiers option is broken:
cat test1.cc
// \u00e4 = ä, \u00f6 = ö, \u00fc = ü, \u00df = ß
int test\u00e4\u00f6\u00fc\u00df ()
{
return 0;
}
gcc -fno-extended-identifiers -c test1.cc
compiles OK (which is actually wrong)
gcc -std=gnu++14 -fno-extended-identifiers -c test1.cc
