Hi,

It seems that the macro bind as defined in trunk/include/ruby/win32.h  
conflicts with added tr1 support to msvc9.0 (which is essentially  
SP1). The conflict arises when \<trunk/include/ruby/win32.h\> is  
included along with visual studio standard tr1 include

\<trunk/include/ruby/win32.h\> defines:

#ifdef bind  
#undef bind  
#endif  
#define bind(s, a, l) rb\_w32\_bind(s, a, l)

has template methods such as  
template\<class \_Ret,  
class \_Fty  
\_C\_CLASS\_ARG0\>  
\_Bind\<\_Ret,  
\_BINDN\<\_Callable\_obj\<\_Fty\> \_C\_ARG0\_ARG1\> \>  
bind(\_Fty \_Val \_C\_ARG0\_A0) // \<— here!  
{ // bind to UDT and user-specified return type  
typedef \_BINDN\<\_Callable\_obj\<\_Fty\> \_C\_ARG0\_ARG1\> \_MyBind;  
return (\_Bind\<\_Ret, \_MyBind\>(\_MyBind(\_Val \_C\_A0\_A1)));  
}

Renaming the macro fixed the problem for compiling the ruby wrappers  
I’m working on.

Any solutions other than renaming are appreciated.

Best regards,  
Christoph
