Using very dark magic. Are you sure you're ready for this?
OK, just kidding. It's only the libstdc++ build that fails. I invested a
few hours earlier this year trying to fix it, but finally decided that it's
not worth the worry. A ported version of libstdc++ for gcc 2.95.3 is
included in Haiku's sources and is built as part of Haiku anyway. So it
doesn't need to be built anymore. So the short answer is: Ignore the
problem. :-)
CU, Ingo
PS: Attached is my respective "notes" file with build instructions.
# version files
legacy/binutils/bfd/version.h
legacy/gcc/gcc/version.c
Note: Also replace version in gcc install instructions
# build binutils
mkdir -p binutils-obj
cd binutils-obj
CFLAGS="-O2" CXXFLAGS="-O2" ../buildtools/legacy/binutils/configure
--prefix=/boot/develop/tools/gnupro --disable-nls --enable-shared=yes
make
cd ..
# build gcc
mkdir -p gcc-obj
cd gcc-obj
CFLAGS="-O2" CXXFLAGS="-O2" ../buildtools/legacy/gcc/configure
--prefix=/boot/develop/tools/gnupro --disable-nls --enable-shared=yes
--enable-languages=c,c++
make bootstrap
