Description

openMP has been enabled to improve the speed of binary operations.

This will only take effect if all of the workspace involved are not Managed (i.e. use the hard drive for storage) as these workspaces are not thread safe and are bound by the speed of the disk not the processor.

Enabled openmp support for binary operations

Hopefully this will be ok on linux as GCC 4.2 should be catered for. for pre gcc 4.2 we should be ok as this is all protected by a #ifdef _openmp

Added windows runtime library to windows installer.

Is there a gcc runtime?

(In [2333]) Fix for pragma definition on linux and included gomp library which doesn't get linked by default. Re #535

(In [2335]) Changed scons script to check for gomp first before it adds it as a dependency. Note that this only seems to be necessary for building shared libraries and not executables, which get linked automatically. Re #535
