Troubles compiling GCC v4.3.3 / 4.4.0

I currently have GCC 4.1.2 installed and working. Unfortunately, this version does not seem to support OpenMP, so I try to install some GCC that does. So far , I tried to compile v. 4.3.3 and v. 4.4.0 , but both encounter the same error
([EDIT:] Since yesterday, I have tried all versions from 4.4.0 through 4.1.2, with every version above 4.1.2 failing with the same error message):

4.1.2 compiled just fine.
configuration was done via
../gcc-4.4.0/configure --prefix=/home/mibeer/prog --enable-threads --with-arch=pentium4 --with-tune=pentium4 --enable-languages=c,c++,fortran --with-gmp=/home/mibeer/prog --with-mpfr=/home/mibeer/prog

I used a separate directory for configuration/compilation. I also tried it without the 'with-arch'/'with-tune' switches, but without success.

Then compilation was started by
make bootstrap

What I get is
gcc -c -g -fkeep-inline-functions -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wcast-qual -Wold-style-definition -Wc++-compat -Wmissing-format-attribute -fno-common -DHAVE_CONFIG_H -I. -I. -I../../gcc-4.4.0/gcc -I../../gcc-4.4.0/gcc/. -I../../gcc-4.4.0/gcc/../include -I../../gcc-4.4.0/gcc/../libcpp/include -I/home/mibeer/prog/include -I/home/mibeer/prog/include -I../../gcc-4.4.0/gcc/../libdecnumber -I../../gcc-4.4.0/gcc/../libdecnumber/bid -I../libdecnumber ../../gcc-4.4.0/gcc/c-lang.c -o c-lang.o

../../gcc-4.4.0/gcc/../libcpp/include/line-map.h:67: Fehler: »CHAR_BIT« ist hier nicht deklariert (nicht in einer Funktion)

I found out, that compilation just continues if I change line 61 in gcc-4.4.0//libcpp/include/line-map.h from:
struct line_map GTY(())
struct line_map GTY()

Unfortunately, then it fails some time later on complaining:
build/gengtype ../../gcc-4.4.0/gcc gtyp-input.list
../../gcc-4.4.0/gcc/../libcpp/include/line-map.h:61: parse error: expected '(', have ')'../../gcc-4.4.0/gcc/../libcpp/include/line-map.h:62: parse error: expected an option keyword, have '{'../../gcc-4.4.0/gcc/../libcpp/include/line-map.h:63: parse error: expected ')', have 'char'../../gcc-4.4.0/gcc/../libcpp/include/line-map.h:63: parse error: expected ')', have '*'make[3]: *** [s-gtype] Fehler 1

I tried to just switch from the '(())' to the '()' version back and forth, but at a certain point there was no further advance ( and I guess the resulting compiler would not have worked that fine...)
I am using Suse Linux 10.2 on a Xeon/P4 box. I cant upgrade the box as do not have the privileges (that is why I install the compilers into my local directory - I did this with GCC 4.1.2 as well). This particular Suse version does not seem to bring a GCC version that supports OpenMP...
Has anyone an idea why this happens and how one could solve this?

Thank you

You need to have correct build toolchain for successful compile of gcc, binutils, and glibc.
See the sites for help compiling gcc:

Thank you for your reply!
If I understand you correctly, one or several of the toolchain are soneway inept for compiling recent versions? This seems quite plausible to me, too, but the configure -skript does not complain about anything - well, I am going to check the links you supplied and see whether there is any incompatibility (did I spell this one right?). Ill post the result as soon as I will be back to the failing machine.

Thank you!
PS: If you want to look at the documentation for installing gcc shipped with the tarball, do you need to create the compiler firstly BEFORE being able to create the documentation telling you how to do this? I tried tried it through
make doc
and what I got was something like
xgcc unable to create executables
( I am not at the particular machine right now so I cant post the actual error message)
Perhaps I mess things up a little bit right now, but if I do not, it seems strange that one needs the compiler be built before being able to access the documentation telling one how it could be built!? (The INSTALL - text file just refers to the documentation you have to build...)
Anyway, this is beyond the scope of this thread
