You can compile 2.95.2 with 2.96, it is not compiler that breaks the
compilation.
You need two more patches besides egcs-libio.patch, particularly backport of
http://gcc.gnu.org/ml/gcc-patches/2000-09/msg00968.html
http://gcc.gnu.org/ml/gcc-patches/2000-10/msg00305.html

An alternative to the first one you can find in gcc-2.96-60 rpm in rawhide,
gcc-libio.patch and should fix the undefined _IO_USER_LOCK and other things,
the latter (in 2.96-60 available as gcc-libio-printf_fp.patch) should
ostream << operator work with float/double/long double types.
