Windows trunk not compiling

[Rodolfo Ochoa]

There is a bug on windows that gives the following error:

1>c:\dev\bug928987\src\util\stl_util.h(315): error C2995: 'std::enable_if<std::tr1::is_signed<_Ty>::value&&std::tr1::is_signed<N2>::value,bool>::type zorba::ztd::ge_min(N1,N2)' : function template has already been defined

The error is described here:
http://stackoverflow.com/questions/9285657/sfinae-differentiation-between-signed-and-unsigned

seems that is an error in the compiler, so the solution is a workaround until the compiler is fixed.

[Paul J. Lucas (paul-lucas)]

I'm still curious as to whether:

typename std::enable_if<ZORBA_TR1_NS::is_integral<N1>::value
                      && ZORBA_TR1_NS::is_unsigned<N1>::value
                      && ZORBA_TR1_NS::is_integral<N2>::value
                      && ZORBA_TR1_NS::is_unsigned<N2>::value,bool>::type

would work.

I tried, didn't work with is_integral...
