PROBLEM: libg++-2.2 won't compile on sparc (os 4.1.2) using gcc-2.3.1

(In fact it's not just libg++, but anything using the right (wrong)
combination of include files, I think, will choke.)

DETAILS: Sam Leffler (sam@sgi.com) reported a few days ago he couldn't
compile libg++ either, using gcc 2.2.2.  The make proceeeds along
until the actual libg++ sources are compiled, and then

> gcc -g -nostdinc++ -I.. -I. -I./../iostream -I./../g++-include  -c AllocRing.cc
> In file included from ./../g++-include/sys/types.h:15, from /usr/include/unistd.h:72, 
> from ./../g++-include/unistd.h:25, from ./std.h:28, from AllocRing.cc:22:
> /usr/include/sys/types.h:24: conflicting types for `wchar_t'
> ./../g++-include/stddef.h:11: previous declaration of `wchar_t'
> *** Error code 1
> make: Fatal error: Command failed for target `AllocRing.o'

He very kindly provided me the following patch:

> change /usr/local/lib/gcc-lib/sparc-sun-sunos4.1/2.2.2/include/stddef.h
> 
> #ifdef __GNUG__
> /* In C++, wchar_t is a distinct basic type,

> typedef unsigned short wchar_t;	/* CHANGED LINE */
> #else
> 
> (~40 lines from the bottom).

Does anyone have any other details on this?  Is this really a bug in
the configuration of gcc, or did I (and, presumably, Sam) screw up
installing gcc?

Thanks for some great tools...
