Configure warns:

Your C++ compiler (g++-2.95 -fnoexceptions -fnortti) is not a GNU C++
compiler!
Either set the 'CXX' environment variable to tell me where
a GNU C++ compiler is, or compile at your own risk.
(This code uses a few GCC extensions and GCC-specific compiler options,
and Linux header files are GCC-specific.)


and later:

configure: WARNING: endian.h:     check for missing prerequisite headers?
configure: WARNING: endian.h: see the Autoconf documentation

And with other things as well. Says it can't compile the linuxmodule.

So, I moved the symbolic links for gcc, g++, and cpp to their 3.3 versions
and replaced them with links to the 2.95 versions. compile rans smoothly,
but the error in compilation remains:

g++ -W -Wall -fno-exceptions -fno-rtti -fvtable-thunks -DHAVE_CONFIG_H
