  23 # NOTES
  24 #
  25 # I tried to force gmake to use the native shell for simplicity, by
  26 # setting SHELL as below, but this didn't work reliably because of
  27 # various case sensitivity niggles.  Specifically, COMSPEC (which is in
  28 # fact usually spelled ComSpec on NT, to make life difficult) typically
  29 # references "cmd.exe" (on NT) when the file is actually called
  30 # "CMD.EXE" on disk for hysterical raisons.  As a result, GNU make
  31 # thinks it doesn't exist (unless compiled with a switch to ignore
  32 # case), and so doesn't change which shell it will invoke to execute
  33 # commands.
  34 #
  35 # It would be possible, though very tedious using just gmake facilities,
  36 # to convert the COMSPEC value to uppercase to solve this problem, but
  37 # it isn't worth it.  That is partly because, even when using the native
  38 # shell, gmake tends to not be happy with backslashes in command
  39 # strings.  The obvious solution is to use forward slashes as much as
  40 # possible, which can be made to work most of the time (putting
  41 # filenames in quotes often helps), but there are still some internal
  42 # cmd.exe commands like `del' and `copy' that won't work with them.
  43 # Although it is possible to convert slashes to backslashes when
  44 # necessary, gmake requires explicitly calling its subst function, which
  45 # nmake does not understand).  For this reason, it is simplest to
  46 # mandate that rm and cp be available, so we can use Unix-format file
  47 # names everywhere.  (Fortunately both MS and GNU make, and the
  48 # respective compilers, are happy with Unix-format names.)
  49 #
  50 # Since we cannot easily force the choice of a particular shell, we must
  51 # make the effort to cope with whichever shell is being used.
  52 # Fortunately, the only command we need to use that is shell specific is
  53 # the testing of a file's existence for the purpose of working out when
  54 # we are copying files to their original location.  That particular
  55 # requirement is abstracted easily enough.
  56 #
  57 # The only other problem area was the change of directory when running
  58 # temacs to dump emacs.exe (where gmake doesn't support cd foo in any
  59 # useful way), but that has been resolved by modifying the Windows
  60 # unexec function slightly to not require the directory change while
  61 # still allowing objects and binaries to be in subdirectories.
  62
  63 # This doesn't work.
