NEEDCONSTEXT

Message        <Context> "<name>" is not constant, but occurs in a
               context that requires a constant expression.  This is
               an extension of the language.

Description    The C89 standard requires that an initializer for an
               automatic aggregate or union type object have an
               initializer that is a list of constant expressions.
               HP C allows non-constants in these initializers.
               This is an extension to C89.  Although this is
               allowed by the C99 standard, other C compilers might
               not successfully compile a program that uses this
               extension.

User Action    Be aware of this if you wish to port the program.
