# Compiler Flags
#
# The compiler flag variables are separated into their individual
# purposes, making it easier to deal with the various tools involved
# in a compile.
#
# These are also divided into global vs. local flags. So for instance,
# CFOPTIMIZE affects Crawl, Lua, and SQLite, while CFOPTIMIZE_L only
# affects Crawl.
#
# The variables are as follows:
# CFOPTIMIZE(_L) - Optimization flags
# CFWARN(_L) - Warning flags
# CFOTHERS(_L) - Anything else
#

# These are really good options for the Intel C++ compiler:
#CFOPTIMIZE := -O2 -parallel

CFOPTIMIZE := -O2
CFOTHERS := -fno-strict-aliasing -pipe $(EXTERNAL_FLAGS)
CFOTHERS_L := -fsigned-char
