I tested it and it works for both VC6 and VC7.  The actual block in 
SDL_blit_A.c is:

#if SDL_ASSEMBLY_ROUTINES
#if defined(__GNUC__) && (defined(__i386__) || defined(__x86_64__))
#define MMX_ASMBLIT 1
#define GCC_ASMBLIT 1
#elif defined(_MSC_VER) && (_MSC_VER >= 1200) && defined(_M_IX86)
/* Dirty hack -- VC6 Processor Pack installs malloc.h that
 * defines _mm_malloc. Luckily, we only need this trick for VC6,
 * and it looks like VC6 will not change anymore */
#include <malloc.h>
#if (_MSC_VER >= 1300) || defined(_mm_malloc)
#define MMX_ASMBLIT 1
#define MSVC_ASMBLIT 1
#endif
#endif
#endif /* SDL_ASSEMBLY_ROUTINES */

I have another issue when compiling dibaudio.c:

c:\code\sdl-1.2.10\src\audio\windib\sdl_dibaudio.c(101) : error C2146: syntax 
error : missing ')' before identifier 'dwInstance'
c:\code\sdl-1.2.10\src\audio\windib\sdl_dibaudio.c(101) : error 
C2081: 'DWORD_PTR' : name in formal parameter list illegal

This is referring to:

/* The Win32 callback for filling the WAVE device */
static void CALLBACK FillSound(HWAVEOUT hwo, UINT uMsg, DWORD_PTR dwInstance,
						DWORD dwParam1, DWORD dwParam2)
{


This only happens when compiling with VC6.
