half is a reserved word in GLSL. This test case also fails on AMD's
closed-source driver. From section 3.6 of the GLSL 1.10 spec:
"The following are the keywords reserved for future use. Using them will
result in an error:
...
long short double half fixed unsigned
..."
We should, however, generate a more useful error message. I've
submitted a bug for this.

Changing the name _half fails with a different error in the linker on
the i965 driver and incorrect results on swrast. I've submitted a bug
for this, and I'll investigate it today.
