This is mostly a long term maintenance improvement.
Many coding styles require elimination of trailing whitespace, and
many editors and source code management configurations automatically
gobble up whitespace. When these tools gobble up whitespace, it
complicates reviewing the meaningful code changes.
By removing whitespace on one patch, it makes future
code reviews much easier.

# Note: During a regular execution, LAPACK might create NaN and Inf
# and handle these quantities appropriately. As a consequence, one
# should not compile LAPACK with flags such as -ffpe-trap=overflow.

They are compiled and included in the liblapack.a archive when
the MAKEDEPRECATED option in the make.inc file is set.
TODO: Add the corresponding behavior to the cmake files.
NOTE: The xGEQPF routines are deprecated but still used by some
non-deprecated routines. They have not been moved to the DEPRECATED
directory.

(Bug reported on Aug 18 2013 by Daniel Strobusch on LAPACK mailing list)
(Bug fixed by Rodney on Aug 19 2013)
This is a problem with gfortran. One need to force gfortran to allocate all
local arrays on the stack. One way to do this is to have the option
-frecursive

First commit, works on my mac! Need to see how to adapt to intel compilers and of course Windows.
LAPACKE is not built by default. Is that OK?
User need to type 'make lapackelib' to generate the lib
I add a couple of examples taken from MKL LAPACKE 'make lapacke_example'

Jason (Riedy) wrote our ( ... his? :) ) ideas about it three years ago:
http://www.netlib.org/lapack-dev/lapack-coding/program-style.html#id2537289
Piotr (Luszczek) has written two subroutines, tested them on few platforms, collected the result on his webpage, and sent emails to the lapackers a few times. See:
http://www.cs.utk.edu/~luszczek/lapack/lamch.html
Theses slamch.f and dlamch.f subroutines were taken from PLASMA-2.1.0.
Change to the LAPACK library:
* move the current LAPACK subroutine slamch.f (resp dlamch.f) as
slamchf77.f (resp. dlamchf77.f),
* take the new slamch.f subroutines (resp. dlamch.f), remove the PLASMA
header, have a LAPACK header, and insert the new routines in the
library.
Minor:
* I would leave these routines compiled with the NOOPT flag.
Problem:
* CLAPACK: no idea how CLAPACK's going to handle this. CLAPACK can rely on
IEEE arithmetic, can relay on float.h, or can rely on the previous
xlamch.f

Those are just cosmetic changes to update version number and various other minor change.
