I'm getting the following error messages at link time which involve an
inline friend function under g++ 2.3.2 on a SPARC and an HP:

2.3.2 on a SPARC:

% g++ -o friend friend.c
ld: Undefined symbol
   _get_a__FR1A
collect: /usr/bin/ld returned 2 exit status

2.3.2 on an HP 730:

g++ -o friend friend.c
ld: Unsatisfied symbols:
   get_a__FR1A (code)
collect: /bin/ld returned 1 exit status

// --------------------------

This code runs fine on a DECstation or SPARC running g++ 2.2.2 or a
DECstation running cfront 3.0.
