How about a simple const variable that will trick MSVC, while not
changing semantics.
How about a function in libs/port or a macro in one of its
headers? I believe
the NAN/INFINITE issue is not specific to wined3d.
With the const variable, msvc compiles the code, but still produces a warning.

Ah, the warning appears only with optimization enabled, that's why I didn't
notice.
port sounds great - but (assuming there shouldn't be any "0x7fc00000" or
"#ifdef _MSC_VER" in the solution) the best I can come up with at the moment
is the following :|
#ifndef INFINITY
static float __infinity(int x)
{
const float zero = x ? 0.0f : 1.0f;
return 1.0f / zero;
}
# define INFINITY __infinity(1)
#endif
#ifndef NAN
static float __nan(int x)
{
const float zero = x ? 0.0f : 1.0f;
return zero / zero;
}
# define NAN __nan(1)
#endif

Alexandre prefers checks in configure that set macros like
HAVE_INFINITY in
config.h. For my own msvc builds I have a hand-written config.h file - I'm not
sure if there's a way to tell configure running in mingw or cygwin to use msvc
as the compiler.
