We haven't written the equivalent bits, no. So both patches make sense:
checking the presence of headers, and using whatever is available,
or fallback to disabling the functionality (and Hurd will get it
automatically when it adds the header support).

Note that it'll need a symbol update to get built. Also it seems the
testsuite has issues with comparing floats:

on hurd-i386 and kfreebsd-i386:
lt-ImathTest: testBoxAlgo.cpp:892: void {anonymous}::boxMatrixTransform(): Assertion `b21 == b2' failed.

on m68k:
lt-ImathTest: testBox.cpp:253: void {anonymous}::testExtendByPoint(const char*) [with T = Imath_2_2::Vec2<float>]: Assertion `b.min == p && b.max == p' failed.

It should probably use approximated comparison, shouldn't it?
