This is correct.

The closest thing I have seen to a standard C++ ABI is the one
being developed for Intel's new IA-64 (Itanium) 64-bit processor:

gcc 3.0 will conform to this ABI, but whether or not the dream
of "compile once, link everywhere" on IA-64 will work with
different compilers is yet to be seen.  And of course, there
is no such ABI under Solaris.
