Hello Wang,

I am guessing that it is the preprocessor assertions (e.g., #cpu(i386))
that are not supported by MSVC.

I suggest you test this by removing them from the file (motor.h)
and recompiling.  The preprocessor variables MSB_First and
LSB_First may not be correct, but at least we will know what
exactly is not supported.

Hi,

When I compile motor 6-4-2 under win32-x86 with vs2008 (cl version
14.00.50727.762), it reports the following errors:

In motor.h(126): #if defined(_WIN32) || #cpu(i386) || defined (_M_IX86)

|| defined (_X86_), the #cpu(i386) assertion confuses compiler. If I split it over two lines

then it works.
#if defined(_WIN32) || defined (_M_IX86) || defined (_X86_)
    #define LSB_First (TRUE)  /* LSB is packed first. */
#elif #cpu(i386)
    #define LSB_First (TRUE)  /* LSB is packed first. */
It seems MSVC does not accept directives mixed.
