/* Update log
*
* Jul 12 2001 FNW: Add a meaningful ID to the communicator name, and switch
* to using the recv_context as the unique_id field.
* Mar 6 2001 JHC: Add mqs_get_comm_group to allow a debugger to acquire
* processes less eagerly.
* Dec 13 2000 JHC: totalview/2514: Modify image_has_queues to return
* a silent FALSE if none of the expected data is
* present. This way you won't get complaints when
* you try this on non MPICH processes.
* Sep 8 2000 JVD: #include <string.h> to silence Linux Alpha compiler warnings.
* Mar 21 2000 JHC: Add the new entrypoint mqs_dll_taddr_width
* Nov 26 1998 JHC: Fix the problem that we weren't handling
* MPIR_Ignore_queues properly.
* Oct 22 1998 JHC: Fix a zero allocation problem
* Aug 19 1998 JHC: Fix some problems in our use of target_to_host on
* big endian machines.
* May 28 1998 JHC: Use the extra information we can return to say
* explicitly that sends are only showing non-blocking ops
* May 19 1998 JHC: Changed the names of the structs and added casts
* where needed to reflect the change to the way we handle
* type safety across the interface.
* Oct 27 1997 JHC: Created by exploding db_message_state_mpich.cxx

/* Notice to developers!!!!
* The following include files with _dbg.h suffixes contains definitions
* that are shared between the debuggger plugins and the OMPI code base.
* This is done instead of including the non-_dbg suffixed files because
* of the different way compilers may handle extern definitions. The
* particular case that is causing problems is when there is an extern
* variable or function that is accessed in a static inline function.
* For example, here is the code we often see in a header file.
*
* extern int request_complete;
* static inline check_request(void) {
* request_complete = 1;
* }
*
* If this code exists in a header file and gets included in a source
* file, then some compilers expect to have request_complete defined
* somewhere even if request_complete is never referenced and
* check_request is never called. Other compilers do not need them defined
* if they are never referenced in the source file.
*
* In the case of extern functions we something like the following:
*
* extern int foo();
* static inline bar(void) {
* foo();
* }
*
* If this code exists it actually compiles fine however an undefined symbol
* is kept for foo() and in the case of some tools that load in plugins with
* RTLD_NOW this undefined symbol causes the dlopen to fail since we do not
* have (nor really need) the supporting library containing foo().
*
* Therefore, to handle cases like the above with compilers that require the
* symbols (like Sun Studio) instead of pulling in all of OMPI into the
* plugins or defining dummy symbols here we separate the definitions used by
* both sets of code into the _dbg.h files.
*
* This means if one needs to add another definition that the plugins must see
* one should either move the definition into one of the existing _dbg.h file or
* create a new _dbg.h file.
