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

# This doesn't work.
