Now I had some time to investigate further.

The usage of the assembler under ccs is the problem. I searched for
other assemblers on my system and found:
root at solewer:/usr# find . -name as -print
./gnu/i386-pc-solaris2.11/bin/as
./bin/as
./sfw/libexec/gcc/i386-pc-solaris2.11/3.4.3/as
./ccs/bin/as
./share/locale/as

But the searchpath of gcc does not search in /usr/gnu:

[ewer at solewer:~/tmp]$g++ -print-search-dirs
...
programs: =/usr/gcc/4.6/lib/gcc/i386-pc-solaris2.11/4.6.2/:/usr/gcc/4.6/lib/gcc/i386-pc-solaris2.11/4.6.2/:/usr/gcc/4.6/lib/gcc/i386-pc-solaris2.11/:/usr/gcc/4.6/lib/gcc/i386-pc-solaris2.11/4.6.2/:/usr/gcc/4.6/lib/gcc/i386-pc-solaris2.11/:/usr/gcc/4.6/lib/gcc/i386-pc-solaris2.11/4.6.2/../../../../i386-pc-solaris2.11/bin/i386-pc-solaris2.11/4.6.2/:/usr/gcc/4.6/lib/gcc/i386-pc-solaris2.11/4.6.2/../../../../i386-pc-solaris2.11/bin/:/usr/ccs/bin/i386-pc-solaris2.11/4.6.2/:/usr/ccs/bin/
...

Programs are only search in the /usr/gcc/4.6 folders. So I made a soft
link from
/usr/gcc/4.6/i386-pc-solaris2.11 -> /usr/gnu/i386-pc-solaris2.11/

After this link the compilation and linking works again without
problems and the
created executeables can run.

But I don't know why this has changed. Because I found that I've
already compiled
programs with the GCC from the SFE repository.
