Ok, there are three issues here:
- actual type definitions. They should be as follows for VC++:
typedef signed char int8_t;
typedef short int int16_t;
typedef int int32_t;
typedef __int64 int64_t;
typedef unsigned char uint8_t;
typedef unsigned short int uint16_t;
typedef unsigned int uint32_t;
typedef unsigned __int64 uint64_t;
- VC++ detection. You can use #ifdef _MSC_VER - the format of .vcproj
ensures that the appropriate version of VC++ is used.
- explicit #include <stdint.h> that is present in a few places. This
must not be done when compiling using VC++ than.

That sounds fine.
Here is a patch against CVS/HEAD that fixes all of these things to my
linking :) Please have a look.
P.S. on the portability note: cairo-png.c line 233 and 234:
static const int PNG_SIG_SIZE = 8;
unsigned char png_sig[PNG_SIG_SIZE];
- this is not valid ANSI C. Unfortunately, the ancient standard
doesn't allow using const int in arrays or case statements, so,
this line generates a VC++ error.
P.P.S. where did PNG surface go?
