  Interesting point.  Upon investigation, it turns out that the MetaWare
  High C++ RTL is increasing the file count.

  When compiled with Borland C++ for OS/2, the program reports a table
  size of 40 (High C++ reported 50).  Upon inspection of the BC++OS2 RTL
  source, it turns out that the BC++OS2 RTL is calling DosSetRelMaxFH in
  its startup code, to ensure that the OS/2 per-process file handle table
  is at least as big as its own tables.

  If I remember, I'll test with Watcom C++ later today.
