Revision Log
+ Updated compilation options for Cognac to squeeze out a bit more performance + Now compiles using the Intel Math headers (mathimf.h) rather than plain math.h on both Win32 and Linux platforms when using the Intel compiler. Gives a small boost to performance on Altix and is essential on Windows

| 13 | // The Intel compiler on windows has an "improved" math library compared to the usual Visual C++ one |
| 14 | // In particular it has a acosh and other similar functions which aren't implemented in Visual C++ math.h |
| 15 | // Note you will get a compile time error if any other header (including system ones) includes math.h whilst mathimf.h |
| 16 | // has been included. As a result system_dep.h must be included FIRST at all times (this prevents math.h from being included). |
