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