# Full Debug Symbols has been enabled on Windows since JDK1.4.1.

# enabled with debug info files ZIP'ed to save space. For VARIANT !=
# OPT builds, FDS is always enabled, after all a debug build without
# debug info isn't very useful. The ZIP_DEBUGINFO_FILES option only has
# meaning when FDS is enabled.
#
# If you invoke a build with FULL_DEBUG_SYMBOLS=0, then FDS will be
# disabled for a VARIANT == OPT build.
#
# Note: Use of a different variable name for the FDS override option
# versus the FDS enabled check is intentional (FULL_DEBUG_SYMBOLS
# versus ENABLE_FULL_DEBUG_SYMBOLS). For auto build systems that pass
# in options via environment variables, use of distinct variables
# prevents strange behaviours. For example, in a VARIANT != OPT build,
# the FULL_DEBUG_SYMBOLS environment variable will be 0, but the
# ENABLE_FULL_DEBUG_SYMBOLS make variable will be 1. If the same
# variable name is used, then different values can be picked up by
# different parts of the build. Just to be clear, we only need two
