Help needed analyzing tests results of a gcc 3.4.4 build.

[BigMan]

I'm trying to install gcc (c & c++ only) on a PowerPC running yellowdog
Linux. Currently gcc 2.95.4 is installed for everyone. I want to
install a newer version only for me and here's what I did:

-downloaded and installed (only for me) DejaGNU; then I executed
"runtest -V":
Expect version is       5.32.2
Tcl version is          8.3
Framework version is    1.4.4

-downloaded and installed (only for me) bintuils version 2.16.91.0.1
(2.15 or newer is required according to
http://gcc.gnu.org/install/specific.html#powerpc-x-linux-gnu);
-I get the following unexpected failures when I execute "make check" in
the binutils obj directory (all other results are as expected):
FAIL: ELF weak func first DSO
FAIL: ELF weak func last DSO
FAIL: ELF weak data first DSO
FAIL: ELF weak data last DSO
FAIL: ELF weak data first DSO common
FAIL: ELF weak data last DSO common

Questions: Are these failures fatal? What problems could they lead to
later? How can I fix these failures?

-downloaded and unpacked (in "GCC/Source/Unpacked") these files:
gcc-core-3.4.4.tar.bz2
gcc-core-3.4.4.tar.bz2.sig
gcc-g++-3.4.4.tar.bz2
gcc-g++-3.4.4.tar.bz2.sig
gcc-testsuite-3.4.4.tar.bz2
gcc-testsuite-3.4.4.tar.bz2.sig

-changed to "GCC/Build" and executed "../Source/Unpacked/configure
--prefix=$PROGRAMS_DIR/GCC --enable-threads=posix
--enable-languages=c,c++"
-executed "make bootstrap"
-executed "make -k check" to test the build and got a lot of lines like
these:
FAIL: gcc.c-torture/compile/20031023-4.c  -O0  (test for excess errors)
FAIL: gcc.c-torture/compile/20031023-4.c  -O1  (test for excess errors)
FAIL: gcc.c-torture/compile/20031023-4.c  -O2  (test for excess errors)
FAIL: gcc.c-torture/compile/20031023-4.c  -O3 -fomit-frame-pointer
(test for excess errors)
FAIL: gcc.c-torture/compile/20031023-4.c  -O3 -g  (test for excess
errors)
FAIL: gcc.c-torture/compile/20031023-4.c  -Os  (test for excess errors)
-I also got a lot of compile failures.

And here's what's bothering me now: Are these failures fatal? How can I
fix them?


Here's some more info about the system:

Any help is welcome.
