[Bug c++/18460] New: -2147483648 not considered an "int"

[jens dot maurer at gmx dot net]

Compiling

const int n = -2147483648;

results in the warning

minus-max.cc:1: warning: this decimal constant is unsigned only in ISO C90

which is wrong: The constant is exactly -2^31, which fits into a (32 bit) int,
thus no automatic conversions to larger types should occur.
