John,

As the weaver is complaining about the line, I doubt that this is a VC6 
specific issue.

RPC_ENTRY is defined as __stdcall, RPC_STATUS as long and IN/OUT are 
just for documentation purposes and defined as nothing, so the line

typedef RPC_STATUS RPC_ENTRY
RPC_IF_CALLBACK_FN (
     IN RPC_IF_HANDLE  InterfaceUuid,
     IN void *Context
     ) ;

expands to

typedef long __stdcall
RPC_IF_CALLBACK_FN (
      RPC_IF_HANDLE  InterfaceUuid,
      void *Context
     ) ;


which should not result in any weaving problems.
I was not able to reproduce your problem, regardless of using the free 
or commercial edition, VC6 headers or newer ones from the PlatformSDK.
I tried the following test application and did not encounter any problems:

// main.cpp
#include <stdio.h>
#include <windows.h>
#include <rpcdce.h>
int main() {

    printf( "Hello from main!\n" );
    return 0;
}

// aspect.ah
#include <stdio.h>
aspect Hello {
    advice execution( "% main(...)" ) : before() {
        printf( "Hello from Aspect :-)\n" );
    }
};

This all makes me believe that the real problem is somewhere else and 
for some reason not detected/reported earlier during the weaving process.
Maybe you can track down the thing to a smaller test app so we can 
reproduce it?

Regards

Daniel
