Correction in installation script for Programming with GNU Software

If you install your software into the directory /usr/cygnus, as
recommended in the install script, you have to perform some extra tasks not
mentioned there.  This is due to a bug in the script, which does not install
the software where the binaries expect it to be.

Contrary to what the script and the README file say, you need to set the
environment variable GCC_EXEC_PREFIX so the gcc compiler finds
subordinate programs like cpp. Also, you have to create a symbolic
link to let Emacs find its Lisp files. These tasks are described in detail
below.

To set GCC_EXEC_PREFIX, check where the directory gcc-lib is after
installation. It will be in a directory of the form:

/usr/cygnus/platform/lib/gcc-lib/

where platform is one of the following, depending on your operating
system:


	OS			platform

	Solaris 2.x		H-sparc-sun-solaris2
	SunOS 4.1.x		H-sparc-sun-sunos4.1.4
	Digital UNIX		H-alpha-dec-osf2.0
	HP-UX			H-hppa1.1-hp-hpux9
	SGI Irix		H-mips-sgi-irix5
	IBM AIX			H-rs6000-ibm-aix3.2.5

Set GCC_EXEC_PREFIX through one of the following commands.  Remember to
include the slash at the end of the pathname. For Bourne shells:

GCC_EXEC_PREFIX=/usr/cygnus/platform/lib/gcc-lib/
export GCC_EXEC_PREFIX 

For C shells:

setenv GCC_EXEC_PREFIX /usr/cygnus/platform/lib/gcc-lib/

The other task you have to do is create a symbolic link to the location of
the files used by Emacs.  Execute the following command as system
administrator (root):

ln -s /usr/cygnus /usr/cygnus/progressive-95q4
