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.
177c0ea7 34#
9e6fd35d
AI
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.)
177c0ea7 49#

AI
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.
177c0ea7 56#
9e6fd35d
AI
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.
