Details:

This applies to the Ocatve Version configured for WIndows install -- Microsoft
Visual Studio 2010 version

The Dynamically Linked Function example Oct-File example in the manual at page
669 (685 of PDF) will not compile.

The compiler indicates that the mkoctfile compiler is not available --
actually it is a broken link to the Microsoft Visual Studio C compiler.

The following is a simple change that will allow compiling an oct file in
Windows 7 and Windows Vista 64

Line 74 of math.h needs to be changed to compile if a 32 bit compiler is used
-- like the C Express compilers.

Note that the only change is to add "(x86)" to line 74 as indicated.

/* Include VC++ original math.h */
#include <c:/Program Files (x86)/Microsoft Visual Studio
10.0/VC/include/math.h>

Using this batch file from a command prompt in the home directory appears to
start Octane 3.6 correctly. This assumes that the Microsoft Visual Studio
Express 2010 C++ compiler is installed.

echo off
cd C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\
call vcvarsall.bat x86
cd C:\Software\Octave-3.6.4\
