# COPT
#
# COPT is for options that the sophisticated builder might want to vary
# from one build to the next, like options to build Postgres with debugging
# information included. COPT is meant to be set on the make command line,
# for example with the command "make COPT=-g". The value you see set here
# is the default that gets used if the builder does not give a value for
# COPT on his make command.
#
# There is a nonobvious relationship between -O (optimization) and
# -Werror (consider all warnings fatal). On some systems, if you don't
# optimize, you will always get some warnings because the system header
# files will include some unreferenced functions in the code. These are
# functions that are supposed to be inline, so there wouldn't ordinarily
# be an "unreferenced" problem, but if you don't enable optimization, no
# inlining can happen, and hence the problem. Therefore, we include
# if you override -O, you override -Werror as well.
