 Dears

 We are using gcc 4.1.2.

 In the boost version '''1.39''' the code like compiles well:

 return unique_ptr<FILE,PIPE_Deleter>(0);

 In the boost '''1.38''' does not.

 The error message is like below and points that during return
 copy ctor is used, which is private, but there is no documentation
 on changes between 1.39 and 1.38 in the unique_ptr interface,
 so for both boost versions code shall be OK.

 Could you look at that issue, please.
