# Definitions for all platforms.
#
# Normally the convention is that these alternate definitions of
#   primary make variables are never defined inside the Makefiles anywhere
#   but are defined via environment variables or set on the make command
#   line. So you should never see an ALT_* variable defined in any
#   makefiles, just used. This is the convention and there are some
#   exceptions, either mistakes or unusual circumstances.
#
# The naming convention for the default value of one of these variables
#   that has an ALT_* override capability is to name the default value with a
#   leading underscore (_). So for XXX you would have:
#      _XXX      default value
#      ALT_XXX   any override the user is providing if any
#      XXX       the final value, either the default _XXX or the ALT_XXX value.
#

# On Directory names. In very rare cases should the Windows directory
#    names use the backslash, please use the C:/ style of windows paths.
#    Avoid duplicating the // characters in paths, this has known to cause
#    strange problems with jar and other utilities, e.g. /a//b/ != /a/b/.
#    Some of these variables have an explicit trailing / character, but in
#    general, they should NOT have the trailing / character.
