Hello experts,
I am in the process of porting Protobuf on WINCE ARM plaform.As i
understood from the mail discussions and googling found that protobuf is
not currently supported on the wince platforms. When i tried to compile
code using visual studio 2008 compiler i am getting following compilation
issues.
>From the compilation errors i understand that atomic operations for arm
wince need to be implemented.

and so on .................................
I checked the error is found to be caused by the line
"GOOGLE_PROTOBUF_ATOMICOPS_ERROR"
// MSVC.
#elif defined(_MSC_VER)
#if defined(GOOGLE_PROTOBUF_ARCH_IA32) || defined(GOOGLE_PROTOBUF_ARCH_X64)
#include <google/protobuf/stubs/atomicops_internals_x86_msvc.h>
#else
GOOGLE_PROTOBUF_ATOMICOPS_ERROR
#endif
#define GOOGLE_PROTOBUF_ATOMICOPS_ERROR \
#error "Atomic operations are not supported on your platform"
Are there any opensource libs which makes use of atomic operations for
wince arm platforms which i can reuse here ? Please suggest me the approach
on how to implement atomic operations for wince arm platform.
