Then you did not run "./configure", you run "./configure --enable-cpp", don't
you?

It just shows how GCC has been configured at build time. Your distribution can
split support for languages into different packages making compiler for C++
unavailable. See <

PCRE 8.30 could enable C++ support even without C++ compiler being available.
The error message says your are missing header files from C standard library.
Therefore the build failed.
You have to install package which contains `g++' executable and
packages which contains the two header files. I think you need
to install packages gcc46-c++, libstdc++46-devel and maybe more. You can use
"zypper wp g++" to find out which package provides a file
(
