+@cindex compressed debug sections
+@value{GDBN} will use the @samp{zlib} library, if available, to read
+compressed debug sections. Some linkers, such as GNU gold, are capable
+of producing binaries with compressed debug sections. If @value{GDBN}
+is compiled with @samp{zlib}, it will be able to read the debug
+information in such binaries.
+
+The @samp{zlib} library is likely included with your operating system
+distribution; if it is not, you can get the latest version from
+@url{http://zlib.net}.
