Compile
int a;
int b = (int)&a;
short c = (short)&a;
on a 32-bit platform:
[EMAIL PROTECTED]:~> gcc -S t.c
t.c:3: error: initializer element is not constant
Reading C99 6.6 §7-10, I understand that the compiler is entitled to accept the
first initializer but not the second. However I find the error message not very
helpful, especially in light of the other case.
The Sun Studio compiler issues:
gax% cc -S t.c
"t.c", line 3: an address is not allowed in a constant initializer for an
integral type whose size is smaller than the size of a pointer
which is much nicer.
