  This problem appears to no longer occur with the latest version of Ice, 3.3.0.

  I just downloaded Ice 3.3.0 and the behaviour appears to be exactly the same:

  Volume in drive T is DATA
  Volume Serial Number is 4CC3-C718
  
  Directory of T:\felix_grid_server\grid_interfaces\src\IceFiles

  What test were you conducting to conclude that this is fixed in Ice 3.3.0?

  The problem appears to be the presence of the GridGateway.ice~ file. If you remove that file then the warning should go away. I also don't see the warning if I run slice2cs from a cygwin window, which is what I originally did to test this. Either way, thanks for the report, we will look into it further.

  Ah thanks! That makes some sense. The Gateway.ice~ file is created by VIM. So looks like it's actually an issue with the wildcard matching... At least now I know what it is so I can work around it... It wouldn't happen with cygwin because the cygwin shell expands the asterix ('*') before it is passed to the program, like UNIX. The issue must be with the wildcard expansion inside slice2cs itself.

  OT question
  
  I am sorry for hijacking this thread but a question to Mr. Collingsworth. Are you the same Paul Collingsworth that used to frequent the discuss.develop.com mailing lists in the glory days of COM/DCOM/ATL when Don Box was still with Developmentor and Al Major/Michael Nelson were still around?

  There is no wildcard expansion inside slice2cs. It simply processes its arguments and, if it sees something that doesn't end with ".ice", it complains.
  
  Presumably, the cmd shell incorrectly expands "*.ice" to include the backup ".ice~" file name, which doesn't end in ".ice", hence the complaint. You can easily test this by checking the output produced by "echo *.ice" in the same cmd shell.
  
  Cheers,
  
  Michi.

  Aargh... I forgot, and Marc just reminded me.
  
  On Windows, you link with setargv.obj to get the wildcard expansion. We do link with setargv.obj for slice2cs. So, I'd say this is a bug in setargv.obj.
  
  You could drop some trace in the main() and print out what is actually passed to the compiler. That will narrow it at least.
  
  Cheers,

  Yeah - more intrinsic to windows than anything else:
  
  T:\felix_grid_server\grid_interfaces\src\IceFiles>dir *.ice
  Volume in drive T is DATA
  Volume Serial Number is 4CC3-C718
  
  Directory of T:\felix_grid_server\grid_interfaces\src\IceFiles

  To clarify what I meant by that last post: because the behaviour is consistent with other windows applications wildcard expansion (i.e. "dir *.ice" returns .ice~ files too), I no longer think that this is a bug in slice2cs.

  I agree. I mean, if you wanted x.ice~ as well, you would say
  
  dir *.ice~
  
  I don't think there is much we could do about this. Who knows what other errors are present in the wildcard expansion...
  
  Cheers,
