19 # Ensure 'all' is the default target
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
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.)
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.
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.
65 # Determine whether make is using sh or cmd/command as shell; cmd.exe
66 # will output "ECHO is on" when echo is given by itself, while sh will
67 # not produce any output.
