The functions in support.h are generally non-portable.  Their interface is
"subject to change without notice" and now you know why their use is
deprecated.

BTW, just in case, it was not ME!

I don't have the slattach sources.  Anyway, it seems like I have already
given the right advice:

#define _unx2dos libc_unx2dos
...
#include <support.h>
...
#undef _unx2dos
...
int _unx2dos (int my, int private, int interface, ...);
...

You see: You don't need the prototype from support.h, so simply #define it
to another name.  As soon as your sources really mean your private
implementation of _unx2dos you #undef it again.  It's not clean, but using
_unx2dos is not clean at all.

If you're unsure what really happens do 

	"gcc -E slattach.c -o slattach.pre"

In "slattach.pre" you will find the preprocessed sources (including all
headers) and you can check if all macros expand as you intended to.

Ciao
