I personally hacked just gcc 3.2.
Not sure it will work with gcc 3.3.x family.
0. Copy gcc-3.2.tar.gz distribution to any directory.
Let's name this directory as "<dist>.
1. Become user "root" and choose a directory where you are going to unpack gcc distribution.
Let's call it <gcc-prefix>.
Then:
cd <gcc-prefix>
2. Unpack distribution gcc-3.2.tar.gz using command "gtar -zxf <dist>/gcc-3.2.tar.gz" (automatically creates top directory gcc-3.2 in <gcc-prefix>)
3. Follow the steps bellow (to fix wchar support problem):
3.1. In directory <gcc-prefix>/gcc-3.2/libstdc++-v3:
remove all occurrences of the words:
"vfwscanf", "vswscanf", "vwscanf", "wcstof"
from the following files:
acinclude.m4 (1 spot)
aclocal.m4 (1 spot)
configure (6 spots)
3.2 In the directory <gcc-prefix>/gcc-3.2/libstdc++-v3/include/c_std/:
file std_cwctype.h:
remove string "using ::iswblank;"
file std_cwchar.h:
remove the following strings:
"using ::vfwscanf;"
"using ::vswscanf;"
"using ::vwscanf;"
"using ::wcstof;"
4. Continue the standard way
4.1 Choose a directory where you are going to create build directory.
Let's call it <build-prefix>. Go there:
cd <build-prefix>
4.2. create build directory (e.g. gcc-3.2-build), create installation directory (e.g. /opt/gcc)
4.3 cd gcc-3.2-build
2.4 <gcc-prefix>/gcc-3.2/configure --prefix=/opt/gcc --enable-threads=posix --enable-languages=c,c++
2.5 make bootstrap. It takes a while.
2.6 make install
Hope it'll help.
