can't reinterpret_cast to/from the same type

[Peter A. Felvegi]

hello,

i don't know if it's a bug, please clarify:

rc.cpp:
------8<------
void f()
{
        int x = 0;
        int y = reinterpret_cast<int>(x);
}
------8<------
gcc -v:

Thread model: posix
gcc version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)

gcc -c rc.cpp:
rc.cpp: In function ‘void f()’:
rc.cpp:4: error: invalid cast from type ‘int’ to type ‘int’

i suspected that one could cast from int to int.

google hasn't found any relevant pages for 'gcc reinterpret cast bug'
