Installing EGCS and BINUTILS together

[wheeler at cipr dot rpi dot edu (Frederick W. Wheeler)]

There have been several questions posted here regarding configuring
EGCS with GLD and GAS.  There are always answers too, so this is by no
means an open question.  Nonetheless, I have accomplished this
configuration in a very straightforward way by installing the egcs
distribution right on top of the binutils distribution, configuring,
compiling and installing.  The configuration/make process recognizes
that the binutils are present and compiles and installs them right
along with gcc.

I am sure that many of the people reading this already know that this
will work.

This was more or less suggested to me by Joe Buck <jbuck@Synopsys.COM>
who added the following important caution:

Briefly, I do this to make the source tree:
  gzip -cd binutils-2.9.1.tar.gz | tar xvf -
  mv binutils-2.9.1 egcs-1.1a
  gzip -cd egcs-1.1a.tar.gz | tar xvf -
then configure with --with-gnu-as and --with-gnu-ld and whatever else.
Some files are overwritten by the second tar.

My full fetch/untar/config/compile/install script is below if you want
more details.

I have used this scheme on Solaris 2.5 and HP-UX 10.20 with eggc-1.1a
and binutils-2.9.1.  Of course, on the HP, gld is not used.  I have
not noticed any problems with the compiler, however, I have not run
the testsuite
