  You're kidding ?

  This could explain a problem that I've been having with the resource
  compiler.

  Ran from within a makefile, with NMAKE invoked from the command line,
  the resource compiler runs fine.

  Ran with NMAKE invoked via another application, it also works fine on
  my machine.

  Ran from the same application, on the same makefile, on a different
  machine that has additional networking software installed, the
  resource compiler complains with error C1017, which is an error
  opening a file, usually PMSHL.H.

  The problem that I've been having, is that (try as I might), I cannot
  find a single file handle leak in the program that invokes NMAKE (I
  even went to the lengths of using OPEN_FLAGS_NOINHERIT on *all* calls
  to DosOpen in the program).

  And until now I found it difficult to believe that the presence of
  Netware Client for OS/2 or Communications Manager/2 (both of which
  were the differing factors in tests) could affect file handle usage.

  Is it possible that other OS/2 device drivers may be erroneously
  *reducing* the number of file handles, in much the same way as the
  MMOS/2 drivers erroneously increased them ?

  Anyone have any information on this (I shall attempt a little more
  investigation myself, of course) ?
