Following link might give some details about Sun Solaris support of

and also ideas how to solve that problem.
Yes, that would work. Any build system guru who could implement that? I think
it is not a good idea to put that into wined3d
Well, we have only one isinf call in Wine so I think it isn't worst of
creating Wine special isinf implementation. Instead I propose emulate
isinf via finite() and isnand() (both coming from ieeefp.h).
