And here is the patch which updates the documenation, it also removes the reference
libf2c which was wrong any ways.  Also --enable-version-specific-runtime-libs is still
the default for libobjc as the headers are still installed in
${libdir}/gcc/${version}/${target}/include.

Thanks,

ChangeLog:
	* doc/install.texi (--enable-shared): Update libobjc's shared library status.
	Remove reference to libf2c.

 Build shared versions of libraries, if shared libraries are supported on

-are enabled by default on all platforms that support shared libraries,
-except for @samp{libobjc} which is built as a static library only by

 If a list of packages is given as an argument, build shared libraries
 only for the listed packages.  For other packages, only static libraries
 will be built.  Package names currently recognized in the GCC tree are
 @samp{libgcc} (also known as @samp{gcc}), @samp{libstdc++} (not
 @samp{libstdc++-v3}), @samp{libffi}, @samp{zlib}, @samp{boehm-gc},
