#ifndef _objasm_problem
#define _objasm_problem

A problem with ObjAsm is the that the headerfile containg the register names, 
only can be included once. If it is included more than one time, you get an
error saying that the registername is already defined.

Here is an example:

; >h.regs

r0 RN 0
r1 RN 1
...

END

; >h.someinclude

GET h.regs

...

END


; >s.some objasm file

GET h.regs
GET h.someinclude

...

END


Now h.regs. will be included twice, resulting in an error. In Ansi-C, this is
cured in an elegant way:

/* >h.include1

#ifndef _h_include1
#define _h_include1

/* body of includefile: */

void function a();
void function b();

struct ...

...

#endif


Now, the body of the includefile is only inserted once. Is something like this
possible in ObjAsm/AAsm?

Ah, good someone else who realises this problem actually exists.

I haven't found any way round this yet, I've just setup my headers carefully
and included them once and only once in the 's' file in the correct order.

Perhaps write a tool which handle #include directives and ignores everything
else?

If you want to do conditional includes in objasm/aasm you need to do someting
like the following (can't be too sure if the is exactly right because my
manuals are on the other side of the world!)


; File to define register names

   [ :NOT::DEF:regs

   GBLL regs


r0 RN  0
r1 RN  1
    .
    :

;  <stuff to include>

   ]

   END

I seem to recall that this does the trick.
