According to [lex.icon], Table 5 of the C++ 0x spec (e.g., N21914), the type
of the integer literal in the snippet below in ILP32 is long long. gcc does
the right thing (i.e., interprets the literal correctly) but the warning it
issues (with -m32 only) is unwarranted.
$ cat t.cpp && g++ -dumpversion && g++ -c -m32 -std=c++0x t.cpp
long long foo ()
{
return 0x123456789abcd;
}
