[Serdev] adding a header from a module

[Ulrich Abend]

Hi all,

please tell me what is the recommended way of adding a new header from a 
module. 
What I tried is to use append_hf() from textops via find_export(), it works, 
but that's not very nice, since the function casts char* to str*, so my 
module now creates a str* casts it to char* so that casting back in 
append_hf()  works.

I also saw in module auth, that the code is copied, shall i copy the function 
append_hf_helper() too?

Thanks,

Uli.
