# Detecting Windows 9X
# We used to run the `ver' command to see if its output contains the
# word `Windows'. If this is true, we are running Windows 95 or later:
#
# ifdef COMSPEC
# # First, check if we have the COMSPEC environment variable, which
# # indicates we can use COMMAND.COM's internal commands
# is_windows := $(findstring Windows,$(strip $(shell ver)))
# endif
#
# Unfortunately, this also detects the case when one is running
# DOS 7.x (the MS-DOS version that lies below Windows) without actually
# launching the GUI.
#
# A better test is to check whether there are both the environment
# variables `winbootdir' and `windir'. The first indicates an
# underlying DOS 7.x, while the second is set only if windows is
# available.
#
# Note that on Windows NT, such an environment variable will not be seen
# from DOS-based tools like DJGPP's make; this is not actually a problem
# since NT is detected independently above. But do not try to be clever!

# Setting COPY is a bit trickier. Plain COPY on NT will not work
# correctly, because it will uppercase 8.3 filenames, creating a
# `CONFIG.MK' file which isn't found later on by `make'.
# Since we do not want that, we need to force execution of CMD.EXE.
# Unfortunately, CMD.EXE is not available on Windows 9X.
# So we need to hack.
#
# Kudos to Eli Zaretskii (DJGPP guru) that helped debug it.
# Details are available in threads of the FreeType mailing list
# (2004-11-11), and then in the devel mailing list (2004-11-20 to -23).
