[Openexr-devel] IlmImf/ImfSystemSpecific.cpp and cpuid

[Richard PALO]

Hi, came across build issues and the above file..
In particular, it fails when building PIC as the asm code doesn't deal 
with all the possible cases...

Fortunately the code was already strobed with __GNUC__, so I updated to 
use the gcc builtin __get_cpuid which does all the work.

I took advantage of the occasion to rectify the ints to be unsigned as 
we're dealing with registers here.

Patch proposal is attached.

Wanting to test this, I came across an issue here as well for SunOS, so 
I add as well a second patch to correctly include unistd.h for this 
platform in IlmImfTest/main.cpp.

Unfortunately the test fails anyway as there is a file not found named 
'comp_dwaa_v1.exr'.  Can't seem to find it anywhere.  Any hints?

cheers
