# 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 good optimizations for a Pentium M or better:
#CFOPTIMIZE := -O2 -march=i686 -mtune=i686 -mmmx -msse -msse2 -mfpmath=sse -funroll-all-loops
# These are really good options for the Intel C++ compiler:
#CFOPTIMIZE := -O2 -parallel
CFOPTIMIZE := -O2
CFOTHERS := -fno-strict-aliasing -pipe
CFOTHERS_L := -fsigned-char
CFWARN := -Wall
MAKEFLAGS := --no-print-directory

# Platform Detection
#
# Use the variable OSNAME if you need to add something that's
# platform-specific.
# The valid OSNAME values are currently:
#    'WIN32': alias for MinGW and Cygwin
#    'MacOS': alias for Darwin (Mac OS X)
# and non-translated values from other platforms (values from
# 'uname -s' call). So Linux is simply 'Linux', etc.
