FTBFS on the Hurd

[umlaeute]

In o3dgcTimer.h#L33 there are some includes protected by an #ifdef __MACH__:

#elif __MACH__
#include <mach/clock.h>
#include <mach/mach.h>
#else
#include <time.h>
#include <sys/time.h>
#endif

It seems that this is intended for OSX/macOS.
However there are other implementations of the Mach Microkernel, notably GNU Hurd, which lacks the mach/clock.h include.
Therefore this file cannot be built on the Hurd.

If the define was indeed meant for OSX/macOS, I suggest to use __APPLE__ instead:

#elif __APPLE__
#include <mach/clock.h>
#include <mach/mach.h>
#else
#include <time.h>
#include <sys/time.h>
#endif

I've also reported this KhronosGroup/COLLADA2GLTF#103 (I guess the code has been taken from there). Nevertheless it would be nice if you could fix that locally as well.

The code came with the glFT-importer. I will take a look.

I just discovered that the proposed fix (replacing __MACH__ with __APPLE__) is not enough to make assimp build on the Hurd.
I'll try to find a real solution in the next days.

Great, thanks a lot for your time and work!

[umlaeute]

ah, found the problem.

in that file, there seem to be two occurences of __MACH__, and both of them have to be replaced with __APPLE__.

See the Debian patch that allows to successfully build assimp on the Hurd.
