Well, it wouldn't just be a rename of the function. It would actually
*set* the field. The caller wouldn't do the direct assignment to
opt->value, but would call a function such as:

openconnect_set_option_value(struct oc_form_opt *opt, const char *value);

I might even *rename* opt->value, to make sure they use the function. Or
maybe even make 'struct oc_form_opt' an opaque structure and make them
do *everything* with accessor functions.

And then yes, the whole API would all be clean of any allocation; no
strings would need to cross the boundary between libraries. Which not
only fixes the Windows situation but is also a fairly nice cleanup. I
think that's probably worth an ABI break, and I can probably fix it up
with wrappers to provide compatibility with the previous soname, like I
did once for libopenconnect.so.1 after libopenconnect.so.2 was
introduced.
