Actually in this case the assumption is realistic. Our C51 compiler is both directive and syntax compatible with the Keil tools. We have extensions that they don't have but their compiler was the standard we wrote to.

This is not a safe assumption at all!

Dealing with with such detailed target-specifics as XDATA, PDATA, etc is <i><b>way</b></i> beyond the scope of ANSI 'C' - therefore any such <b>extensions</b> provided by any particular implementation <i><b>must</b></i> be considered to be non-portable!

Of course, one would hope that all 'C' compilers targetted at the 8051 would provide <i>some</i> way to achieve this, and they might even provide <i>similar</i> ways, but you cannot assume that they will provide precisely the <i>same</i> way!
