Howdy, 

Just when I thought C++ would add some productivity to my existence all hell
breaks loose (forgive me please, it is late, very late). I am having severe 
problems with C++ and Apollo C System files compatability.

Can someone, anyone shed some light ?

The situation is as follows. I am programming in C++ Version 1.2.1 under SR10.1
with SR10? release of C (I think). Anyway the C++ language works well so the C
must be later that V6.00. The problems are with Header Files, that seem to be
incompatible with this C++ (but not the C). For example ..

The following code (I know some of them ain't C++ files ie stdio.h is not ) 

#include	<stdio.h>
#include 	<string.h>
#include 	<apollo/base.h>
#include 	<apollo/pad.h>
#include 	<apollo/error.h>
#include 	<apollo/ios.h>
main() {
}

when compiled with ver sys5.3 /bin/ccxx ... yields the following errors and 

	[NOTE I AM USING THE SYS5.3 FILES from BSD (is this a problem ?)]

"/usr/include/apollo/base.h", 
line 109: error: high  __attribute : type expected (high  is not a  type name)
line 109: error: bad base type: type name high 
line 109: error:  argument type expected for __attribute()

caused by the new __attribute in the following I believe

      10/10/88 cas   make sizeof time_$clock_t alignment insensitive
                     change #attribute to __attribute

#if _ISP__M68K || _ISP__A88K 
	time_$clockh_t high __attribute((aligned(1)));

and these errors

"/usr/include/apollo/ios.h", 
line 570: error:  function declaration in argument list ( ios_$set_locate_buffer_size())
line 577: error:  function declaration in argument list ( ios_$switch())
line 627: error:  function declaration in argument list ( ios_$inq_path_name())
Sorry, too many errors

caused by the #options statement in the following I believe

ios_$get_handle( 
    ios_$id_t   &strid,
    uid_$t      &type_uid,
    status_$t   *status
) #options(a0_return);

extern void
ios_$set_locate_buffer_size(
    ios_$id_t   &id,
    short       &size,
    status_$t   *status
);

It seems to me that the C++ is lagging behind the C but I am not sure, it
could easily be just stupid mistakes on my behalf. But alas, it is very
frustrating.

The release notes for the C++ recommend the use of these very /usr/include
/apollo/*.h header files (cos they have the prototyping and variable reference
included.)

HELP: 
	Could someone (perhaps at Apollo) please set me straight once and for
	all about what version of what goes with what in this C++ system call
	situation.

Thanks In Advance,
Ashley Aitken.
