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.
177c0ea7 33#
9e6fd35d
AI
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.)
177c0ea7 48#

AI
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.
177c0ea7 55#
9e6fd35d
AI
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
62# This doesn't work.
