--- Comment #7 from Keith Kriewall <keith.kriewall at attachmate.com> ---
In case it helps, it appears that MSVC always treats enum values as signed int.
 E.g. see:
 
http://compgroups.net/comp.lang.c++/problem-with-visual-c++-7.1.3088-and-bit-fields/1013665

GCC appears to use unsigned int if no enum values are negative.
 
http://gcc.gnu.org/onlinedocs/gcc-4.1.1/gcc/Structures-unions-enumerations-and-bit_002dfields-implementation.html

The implication is that bit-fields may be a bit short if specified as GLuint.
