bullet/LinearMath/btScalar.h:337:14: warning: ‘btInfinityMask’ defined but not used

When I compiling OpenMW sources (which is using Bullet library for physics) I 
see warning about unused variable btInfinityMask in bullet (maybe it would be 
better to use enum { btInfinityMask = something }; instead of static int?).

What is the expected output?
No warnings at all. 

What do you see instead?

What version of the product are you using? On what operating system?
Bullet 2.82, compilation was done on Arch Linux (64bit) with GCC 4.8.2 

If you need any additional information just let me know and I will try to 
provide it.
