A piece of code, Microsoft and Intel compiler can, arm

 
The class vec_32bitstuff: public vec_data 
{
Public: 
//Constructors and converters up from the base type. 
The inline vec_32bitstuff () {} 
The inline vec_32bitstuff vec_data (z) : vec_data (z) {} 
. 
. 
. 
} 

The class vec_float: public vec_32bitstuff 
{
Public: 
The inline vec_float () {} 
# ifdef INTEL_SIMD 
The inline vec_float __m128 (z) : vec_32bitstuff (z) {} 
# endif 
The inline vec_float vec_32bitstuff (z) : vec_32bitstuff (z) {} 
The inline vec_float vec_data (z) : vec_32bitstuff (z) {} 
. 
. 
}

The above code, vs and interl are good, but the arm - GCC when using vec_float
Error: the call of overloaded 'vec_32bitstuff (const vec_int)' is ambiguous

Because use vec_float place too much, just want to change the base class, how do I change?
