Ok. My steps for build without --enable-threads=solaris:

$ tar xf ../dist/gcc-4.1.1.tar.bz2
$ cd gcc-4.1.1
$ mkdir objdir
$ cd objdir
$ ../configure --prefix=/home/gcc --enable-languages=c,c++
--enable-shared=libstdc++ --disable-multilib --disable-nls
sparc64-sun-solaris2.9
...
$ make
...
$ make install
...
$ /home/gcc/bin/gcc -v
Using built-in specs.
Target: sparc64-sun-solaris2.9
Configured with: ../configure --prefix=/home/gcc
--enable-languages=c,c++ --enable-shared=libstdc++ --disable-multilib
--disable-nls sparc64-sun-solaris2.9
Thread model: posix
gcc version 4.1.1

With --enable-threads=solaris i have a same error:
