After some investigation and testing ,the best solution I found is to use union
gl_constant_value to store the values(vtx.attrptr) instead of storing them in a
float. That involve to update all the dependency and use a new defined macros
like this:

#define ATTR( A, N, T, V0, V1, V2, V3 )      ATTR_##T(A, N, T, V0, V1, V2, V3) 

#define ATTR_GLuint( A, N, T, V0, V1, V2, V3 ) \
    ATTR_UNION(A, N, T, UINT_AS_UNION(V0), UINT_AS_UNION(V1),
UINT_AS_UNION(V2), UINT_AS_UNION(V3))
#define ATTR_GLint( A, N, T, V0, V1, V2, V3 ) \
    ATTR_UNION(A, N, T, INT_AS_UNION(V0), INT_AS_UNION(V1), INT_AS_UNION(V2),
INT_AS_UNION(V3))

The old ATTR became ATTR_UNION and treat the input values(V1,...,V4) as
gl_constant_value union.
