64-bit c,c++ on sparcv9-sun-solaris2

[sigsegv at rambler dot ru]

Greetings, I've been trying to compile 64-bit (i.e. the compiler itself 
in 64-bit binary format) gcc for c,c++ languages. This is done on 
Ultra10 running Solaris 9. c compiler builds OK, but when it comes to 
building c++ it gives the following error message:

make[4]: Entering directory 
`/usr/opt/pkg_build/gcc-3.4.2-build/sparcv9-sun-solaris2/sparcv7/libiberty/testsuite'
make[4]: Nothing to be done for `all'.

`/usr/opt/pkg_build/gcc-3.4.2-build/sparcv9-sun-solaris2/libstdc++-v3'
make: *** [all-target-libstdc++-v3] Error 2

Any ideas what could be wrong?

Below is a script fragment which confiugres and builds gcc

# build a tmp compiler which generates 64-bit code by default
# use this compiler to build a native 64-bit compiler
pkg_build () {
CONFIG_SHELL=/bin/ksh
export CONFIG_SHELL
