Consider moving ACE_MAKE_QWORD so this include isn't needed.

What about the ACE_OS::stat functions, do they have the same problem?

stp->st_atime = ACE_Time_Value (fdata.ftLastAccessTime).sec ();
stp->st_mtime = ACE_Time_Value (fdata.ftLastWriteTime).sec ();
stp->st_ctime = ACE_Time_Value (fdata.ftCreationTime).sec ();
