 {\tt sizeof} operator as they can't be tested by the preprocessor but it is
 sometimes desirable to test them at the compile time.
 
+Note that this macro internally declares a struct whose name it tries to make
+unique by using the {\tt \_\_LINE\_\_} in it but it may still not work if you
+use it on the same line in two different source files. In this case you may
+either change the line in which either of them appears on or use the 
+\helpref{wxCOMPILE\_TIME\_ASSERT2}{wxcompiletimeassert2} macro.

+This macro is identical to \helpref{wxCOMPILE\_TIME\_ASSERT2}{wxcompiletimeassert2} 
+except that it allows you to specify a unique {\it name} for the struct
+internally defined by this macro to avoid getting the compilation errors
+described \helpref{above}{wxcompiletimeassert}.
