+One @value{GDBN} configuration can debug binaries for multiple operating

+@value{GDBN} will autodetect the @dfn{OS ABI} (Operating System ABI) in use,

+One example where this is useful is in debugging of binaries which use

+not have the same identifying marks that the standard C library for your
+platform provides.
