+[Q16]	``When I use GNU libc on my Linux system by linking against
+	  to libc.so which comes with glibc all I get is a core dump.''
+
+[A16] {UD} It is not enough to simply link against the GNU libc
+library itself.  The GNU C library comes with its own dynamic linker
+which really conforms to the ELF API standard.  This dynamic linker
+must be used.
+
+Normally this is done by the compiler.  The gcc will use
+
+	-dynamic-linker /lib/ld-linux.so.1
+
+unless the user specifies her/himself a -dynamic-linker argument.  But
+this is not the correct name for the GNU dynamic linker.  The correct
+name is /lib/ld.so.1 which is the name specified in the SVr4 ABi.
+
+To change your environment to use GNU libc for compiling you need to
+change the `specs' file of your gcc.  This file is normally found at
+
+	/usr/lib/gcc-lib/<arch>/<version>/specs
+
+In this file you have to change a few things:
+
+- change `ld-linux.so.1' to `ld.so.1'
+
+- remove all expression `%{...:-lgmon}';  there is no libgmon in glibc
+
+
+Things are getting a bit more complicated if you have GNU libc
+installed in some other place than /usr, i.e., if you do not want to
+use it instead of the old libc.  In this case the needed startup files
+and libraries are not found in the regular places.  So the specs file
+must tell the compiler and linker exactly what to use.  Here is for
+example the gcc-2.7.2 specs file when GNU libc is installed at
+/home/gnu:

+[A17] {RM} Believe it or not, stat and lstat (and fstat, and mknod)

+{UD} The Linux ldconfig file probably generates a link libc.so ->
