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. | |
