#
# Makefile for native Windows version of Dire Wolf.
#
#
# This is built in the Cygwin environment but with the 
# compiler from http://www.mingw.org/ so there is no
# dependency on extra DLLs.
#
# The MinGW/bin directory must be in the PATH for the 
# compiler.  e.g.   export PATH=/cygdrive/c/MinGW/bin:$PATH
#
# Failure to have the path set correctly will result in the
# obscure message:     Makefile.win:... recipe for target ... failed. 
#
# Type "which gcc" to make sure you are getting the right one!

# People say we need -mthreads option for threads to work properly.
# They also say it creates a dependency on mingwm10.dll but I'm not seeing that.

#TODO: put -Ofast back in.

#	------	-----------------
#	119.8	-O2	Used for version 0.8
#	 92.1	-O3
#	 88.7	-Ofast  (should be same as -O3 -ffastmath)
#	 87.5	-Ofast -march=pentium
#	 74.1	-Ofast -msse
#	 72.2	-Ofast -march=pentium -msse
#	 62.0	-Ofast -march=pentium3   (this implies -msse)
#	 61.9	-Ofast -march=pentium3 -msse
#
# A minimum of Windows XP is required due to some of the system
# features being used.  XP requires a Pentium processor or later.
# The DSP filters can be sped up considerably with the SSE instructions.
# The SSE instructions were introduced in 1999 with the 
# Pentium III series.  
# SSE2 instructions, added in 2000, don't seem to offer any advantage.
#
# For version 0.9, a Pentium 3 or equivalent is now the minimum required
# for the prebuilt Windows distribution.
# If you insist on using a computer from the previous century,
# you can compile this yourself with different options.
