+ * The Symbol _XtInherit is used in two different manners.
+ * First it could be used as a generic function and second
+ * as an absolute address reference, which will be used to
+ * check the initialisation process of several other libraries.
+ * Because of this the symbol must be accessable by all
+ * client dll's and applications. In unix environments
+ * this is no problem, because the used shared libraries
+ * format (elf) supports this immediatly. Under Windows
+ * this isn't true, because a functions address in a dll
+ * is different from the same function in another dll or
+ * applications, because the used Portable Executable
+ * File adds a code stub to each client to provide the
+ * exported symbol name. This stub uses an indirect
+ * pointer to get the original symbol address, which is
+ * then jumped to, like in this example:
+ *
+ * --- client --- --- dll ----
+ * ...
+ * call foo
+ *
+ * foo: jmp (*_imp_foo) ----> foo: ....
+ * nop
+ * nop
+ *
+ * _imp_foo: .long <index of foo in dll export table, is
+ * set to the real address by the runtime linker>
+ *
+ * Now it is clear why the clients symbol foo isn't the same
+ * as in the dll and we can think about how to deal which
+ * this two above mentioned requirements, to export this
+ * symbol to all clients and to allow calling this symbol
+ * as a function. The solution I've used exports the
+ * symbol _XtInherit as data symbol, because global data
+ * symbols are exported to all clients. But how to deal
+ * with the second requirement, that this symbol should
+ * be used as function. The Trick is to build a little
+ * code stub in the data section in the exact manner as
+ * above explained. This is done with the assembler code
+ * below.
