 152 # versus the FDS enabled check is intentional (FULL_DEBUG_SYMBOLS
 153 # versus ENABLE_FULL_DEBUG_SYMBOLS). For auto build systems that pass
 154 # in options via environment variables, use of distinct variables
 155 # prevents strange behaviours. For example, in a BUILD_FLAVOR !=
 156 # product build, the FULL_DEBUG_SYMBOLS environment variable will be
 157 # 0, but the ENABLE_FULL_DEBUG_SYMBOLS make variable will be 1. If

 162 # build.
