Why ``Aaaaargh!''? Is this not ok?

I'm quite confused about  gcc and egcs.   Which libstdc++ should I use
now? Can  the  same libstdc++ be  used by  both, gcc and  egcs, or are
there different versions of   libstdc++?  I  have the  following   one
installed:

mike@example.com mnt/cdrom/RedHat/RPMS$ rpm -qi libstdc++-devel-2.8.0-14           
Name        : libstdc++-devel             Distribution: Manhattan

Summary     : Header files and libraries for C++ development
Description :
This is the GNU implementation of the standard C++ libraries.  This
package includes the header files and libraries needed for C++
development.

Because ``egcs'' and ``cygnus''   are mentioned here, I   am wondering
whether this is a special version of libstdc++ only for egcs.

Also   strange  is  that   the  info-files  /usr/info/libg++.info* and
/usr/info/iostream.info* were gone after I upgraded from Redhat 5.0 to
Redhat 5.2. I copied the old ones from Redhat  5.0 into /usr/info, but
maybe  they  were  removed  on purpose,  because they  give misleading
information when using egcs as the C++ compiler?

Does egcs have its own info-files for the standard C++ library? If so,
why are they missing on Redhat 5.2?

Mike
