Hi,
i have an application written in pure C using Borland C++ 5.02. When 
changing to C++ Builder 6 i had to do slight changes.
For the  time being i want to have the possibility to compile the code 
using both compilers. I tried to use the predefined macro
__BORLANDC__ to distinguish which compiler is used. In the code i wrote:

if (__BORLANDC__ == 0x500)  // tried also 0x502
  {
     ver 5.02
  }
 else
  {
     c++ builder
   }

In the help of ver 5.02 it was written that __BORLANDC__ return 0x500. 
Trying to use it in my code i got warning
"Unreachable code" for the code of ver 5.02 !! . Did i used the macro 
correctly ? if  yes, why i got this warning,  if not
how it should be used ? A small example will be great.

Thanks

Ofer
