The following compiler error message is said to happen because the
program violates the standard. According to the compiler team,
using 'const int' as the key type for map<> is invalid because Row 1 of
Table 69 seems to says that the key must be assignable and therefore
non-const.

1. Is this correct? (that you cannot use const type keys)
2. If so, what is the reason? Many compilers (like gcc) are able to
implement all functions of map<> with const key types.

Thanks,
Anjul.
