[LLVMdev] problem building gcc4 front end on fedora core 5

[Ram Bhamidipaty]

I'm getting a build error when trying to build gcc4 from sources. This is
for the recent 1.9 release.

How I built llvm-1.9:
-----------------------------
tar zxf llvm-1.9.tar.gz
cd llvm-1.9/
./configure --prefix=/custom/llvm-1.9
make ENABLE_OPTIMIZED=1 OPTIMIZE_OPTION='-O2' tools-only
make install

How I built gcc4:
-----------------------------
export PATH=/custom/llvm-1.9/bin:.../llvm-1.9/Release/bin:$PATH
tar zxf llvm-gcc4-1.9.source.tar.gz
mkdir llvm-gcc4-1.9.build
cd llvm-gcc4-1.9.build

../llvm-gcc4-1.9.source/configure --prefix=/custom/llvm-1.9-gcc4
--enable-languages=c,c++ --enable-checking --with-llvm=...../llvm-1.9
--disable-threads --program-prefix=llvm-

make

-------------------

This results in the following error:

Can anyone suggest some things I can do to figure out the source of the
problem?

Thanks for any info.
