Change README

Changing README again.
Describes evolution of Example revisions.

Priority clause in tasks

Add SIMD examples (299), misc changes to 4.0.1 (342)

enacts trac ticket 299 (SIMD examples), 342 (misc changes to 4.0.1) for 4.0.2.

Reference to github and make changes

Created VER in Title page for version (to be used in Introduction).
Inserted git references in Title page and Introduction
Changed Makefile so that clean works
Makefile now creates a zip and tar.gz file with version number (from VER in title page)

Target depend example

Select just C or FORTRAN for compilation

I t would be nice to be able to compile just the C examples; I don't work in FORTRAN, so they just take up space for me.

Correct a few test examples to return a value from main.

A few cases did not have a return value specified for main(). The following pull-request fixes this: #1

Binding correction and page footers

There seems to be an issue with the position of the binding correction and page footers (page number etc.) in both the OpenMP Specification and Examples document. The front matter (table of contents) in both books ends on an odd page, with binding correction on the left and page footers on the right. This page is immediately followed by the first page of the body matter (Introduction) which also has the binding correction on the left and page footers on the right. When producing bound printed copies of the books this will result in the line numbers and page footers in the body matter appearing next to and very close to the binding. We have worked around this issue by inserting a blank page between front matter and body matter. Could this blank page be included in the official versions of the documents?

Continuation markers in Fortran example

You may wish to look at the continuation markers in the following:

https://github.com/OpenMP/Examples/blob/v4.0.2/sources/Example_icv.1f.f

This will not always compile; for example I have tested it with numerous versions of gcc (from 4.4.6 to 4.9.3), portland (12.10 to 15.7), and intel compilers (14.0). The following snippet is an example

gfortran -fopenmp icvb.f90 -o icvbf
icvb.f90:23.67:
       print *, "Inner: max_act_lev=", omp_get_max_active_levels(),
                                                                   1
Error: Expected expression in PRINT statement at (1)
icvb.f90:24.6:
     &           ", num_thds=", omp_get_num_threads(),
      1

I think you need to put the continuation markers at the end of the line, not at the beginning of a new line.

Hope this helps,
