IRIX 6.5

The file consisting of a single line

#include <new>

won't compile under IRIX 6.5, if I try
to compile it using "-mips3" or "-mips4"
without explicitly specifying "-mabi=...".
Instead I get the error message

.../include/g++-v3/new:55: `operator new' 
   takes type `size_t' (`long unsigned int') as first parameter
.../include/g++-v3/new:56: `operator new' 
   takes type `size_t' (`long unsigned int') as first parameter

etc. According to the documentation mabi should
default to 64 when using "-mips3" or "-mips4".
This seems to be the case for the compiler.
The preprocessor however gets the symbols of the mabi n32.
>How-To-Repeat:
g++ -mips4 -c MabiBug.cpp (for the error message)
g++ -mips4 -dM -E -c MabiBug.cpp (for the wrong symbols)
g++ -mips4 -mabi=64 -dM -E -c MabiBug.cpp (for the correct symbols))
