[Error] platmisc.h:26: error: unexpected token `0' in conditional

[Jeremy]

Hi guys, I'am using OMNeT4.6 in ubuntu, and it works very well via IDE or command line. 

The following error prompted  when I tried to use ac++ command(AspectC++) to  combine the txc1.cc (example tictoc attached in OMNeT) with aspect.ah file.

               omnetpp-4.6/include/platdep/platmisc.h:26: error: unexpected token `0' in conditional

The 22nd to 27th line codes of platmisc.h are as following:

// Breaking into the debugger

//

#if defined _MSC_VER

#define DEBUG_TRAP  __asm {int 3}  // Visual C++: debug interrupt

#elif defined _WIN32 and defined __GNUC__

#define DEBUG_TRAP  asm("int $3\n")  // MinGW or Cygwin: debug interrupt with GNU syntax

Could anybody help me?  Why or what condition can this error prompt?

Any solutions?

Thanks a lot in advance!
