the latest release of gcc does not currently support the latest C++-standard
with regard to its implementation of the standard C++-library.
See my other reply (subject "Re: C and C++ library docs")

if you want to distribute programs, you probably don't want to use the new
features of libstdc++-v3, but instead the (portable) subset included
with gcc-2.95.2.
For the headers, you can create symlinks.

try
felix@home:~ > gcc -v
Reading specs from /usr/lib/gcc-lib/i486-linux/egcs-2.91.60/specs
gcc version egcs-2.91.60 19981201 (egcs-1.1.1 release)

to find out where g++ puts its headers (in this case the prefix
is /usr, so the headers are in /usr/include/g++-version)
