[Piglit] MSCV build problem in piglit-util.h

[Brian Paul]

Hi Emil,

This from our automated build.

I think the warnings can be ignored for now, but there's an error:

tests\util\piglit-util.h(196) : warning C4056: overflow in 
floating-point constant arithmetic
tests\util\piglit-util.h(207) : error C2440: 'initializing' : cannot 
convert from 'const char *' to 'char *'
         Conversion loses qualifiers
tests\util\piglit-util.h(196) : warning C4056: overflow in 
floating-point constant arithmetic
tests\util\piglit-util.h(196) : warning C4056: overflow in 
floating-point constant arithmetic
tests\util\piglit-util.h(196) : warning C4056: overflow in 
floating-point constant arithmetic
tests\util\piglit-util.h(196) : warning C4056: overflow in 
floating-point constant arithmetic
tests\util\piglit-util.h(196) : warning C4056: overflow in 
floating-point constant arithmetic

It's not obvious to me what's wrong though.  My local piglit-on-MSVC 
setup isn't working ATM...
