Those are the two of the three options I found. The third suggestion I
found was to cast the initializer to a const WCHAR [], like this (just
using char here for testing outside of wine):

static const struct
{
    const char *foo;
    int bar;
}
test[] =
{
    {(const char []){'a', 'b', 'c', 0}, 5},
};

But that seems to be a C99 feature
(http://gcc.gnu.org/onlinedocs/gcc/Compound-Literals.html).

The other thing I noticed is that even my big fat C/C++ book is
completely clueless about this and (somewhat relatedly) initializes a
(non-const) char * with a string literal and later sprintf()s to it.
