you are not paying attention to the issue. the issue is that this constant is
causing a compiler warning when it should not, and the compiler is treating a
valid signed constant as an unsigned integer.
I recompiled with added -fno-strict-aliasing -fwrapv arguments and I got this
message.
it should NOT be unsigned!
maxint64-bug.cpp:4:19: warning: integer constant is so large that it is
unsigned [enabled by default]
maxint64-bug.cpp:4:5: warning: this decimal constant is unsigned only in ISO
C90 [enabled by default]
