As can be seen from the configure options, this is with GNU
binutils 2.16.1.
I also tried the Sun assembler and linker, and get similar errors
but thousands of times instead of just 7. Complete logs available
on request (1.2 Mb for GNU as/ld, 91 Mb for Sun as/ld; respectively
54k and 2553k compressed with bzip2).
Am I doing something wrong? (--enable-bootstrap=yes gives the same
errors).
Incidentally, the options mention
/export/home/lbre/opt/gcc-4.1.0.tmp/sparc-sun-solaris2.8/
in four places (-B and -isystem options) but this is incorrect
because that directory does not exist yet. I don't think
the bootstrap procedure should ever refer to the install
directory, except when installing. Is this worth another PR?

What's the configure shell? What's the version of GNU make? What's the
bootstrap compiler?

Both sets of tools are known to work with GCC 4.1.0 on SPARC/Solaris 8.

What happens if you bootstrap the compiler (make bootstrap instead of make)?

2.8.1
(that's from GNAT 3.15p, binary distribution from AdaCore; but the
compiler used to build strstream.cc is ./xgcc, i.e. GCC 4.1.0
built in stage1. And, as I said, the same errors occur with
--enable-bootstrap=yes, so I can confidently say that the
bootstrap compiler is irrelevant).
I've started the "make bootstrap" and will report later. To speed it up
I've only passed --enable-languages=c,c++.

--enable-bootstrap=yes has not been tested with GCC 4.1.x so I'd avoid it.

--enable-bootstrap=no + "make bootstrap" cause a successful build:

(no output)
The bootstrap then completes successfully.
So: "make" fails, "make bootstrap" works, but the commands
invoked are identical. Could it be that gcc 2.8.1 silently
miscompiled cc1plus in the case of "make", and introduced an
obscure bug which only strstream.cc triggers?

Most likely, yes; --enable-bootstrap=yes should have worked around the problem,
but it may have its own problems in 4.1.x.
