Synopsis: initializer element is not constant
State-Changed-From-To: open->closed
State-Changed-By: rth
State-Changed-When: Mon Apr 29 18:25:50 2002
State-Changed-Why:
Not a bug. Constant data does not a constant expression make.
See section 6.6 of the ISO C standard. In part:
An integer constant expression shall have integer type and shall only have operands
that are integer constants, enumeration constants, character constants, sizeof
expressions whose results are integer constants, and floating constants that are the
immediate operands of casts. Cast operators in an integer constant expression shall only
convert arithmetic types to integer types, except as part of an operand to the sizeof
operator.
