Windows optimized make.bmk:

@define addlib
	globals.Add("libs", arg1)
@end

## adds a cc_opt option
@define addccopt
	globals.AddOption("cc_opts", arg1, arg2)
@end

@define addwin32ccopt
	if bmk.Platform() == "win32" then
		globals.AddOption("cc_opts", arg1, arg2)
	end
@end

@define addmacccopt
	if bmk.Platform() == "macos" then
		globals.AddOption("cc_opts", arg1, arg2)
	end
@end

@define addlinuxccopt
	if bmk.Platform() == "linux" then
		globals.AddOption("cc_opts", arg1, arg2)
	end
@end

## removes a cc_opt option
@define rmccopt
	globals.Remove("cc_opts", arg1)
@end

@define addldopt
	globals.AddOption("ld_opts", arg1, arg2)
@end

# compiles the specified file, using the current options.
@define make
	make.Make(arg1)
@end

# the default ccopts
# used for compiling c-type files
@define default_cc_opts

	if bmk.Platform() == "macos" then
		# compile for 10.3 ?
		# macos version >= 0x1050 ?
		if tonumber(%macos_version%) >= 4176 then
			globals.Addoption("cc_opts", "osversion", "-mmacosx-version-min=10.3")
		end
		
	elseif bmk.Platform() == "win32" then

		globals.AddOption("cc_opts", "arch", "-march=pentium")
		globals.AddOption("cc_opts", "fastmath", "-ffast-math")
		
	elseif bmk.Platform() == "linux" then

		globals.AddOption("cc_opts", "aliasing", "-fno-strict-aliasing")
		globals.AddOption("cc_opts", "arch", "-m32")
		globals.AddOption("cc_opts", "fancymath", "-mfancy-math-387")

	end

	globals.AddOption("cc_opts", "exceptions", "-fno-exceptions")
	globals.AddOption("cc_opts", "linker", "-c")
	globals.AddOption("cc_opts", "optimization", "-Os")
@end

The Linux make.bmk:

@define addlib
	globals.Add("libs", arg1)
@end

## adds a cc_opt option
@define addccopt
	globals.Add("cc_opts", arg1)
@end

## removes a cc_opt option
@define rmccopt
	globals.Remove("cc_opts", arg1)
@end

@define addldopt
	globals.Add("ld_opts", arg1)
@end

# compiles the specified file, using the current options.
@define make
	make.Make(arg1)
@end

# the default ccopts
# used for compiling c-type files
@define default_cc_opts
	
	if bmk.Platform() == "macos" then
		
		# compile for 10.3 ?
		# macos version >= 0x1050 ?
		if tonumber(%macos_version%) >= 4176 then
			globals.Add("cc_opts", "-mmacosx-version-min=10.3")
		end
		
		# defaults -- normal
		globals.Add("cc_opts", "-fno-exceptions")
		globals.Add("cc_opts", "-c")
		globals.Add("cc_opts", "-Os")
		
	elseif bmk.Platform() == "win32" then
		
		globals.Add("cc_opts", "-march=pentium")
		globals.Add("cc_opts", "-ffast-math")
		
		# defaults -- optimizations
		globals.Add("cc_opts", "exceptions", "-fno-exceptions")
		globals.Add("cc_opts", "linker", "-c")
		globals.Add("cc_opts", "optimization", "-Os")
		
	elseif bmk.Platform() == "linux" then
		
		globals.Add("cc_opts", "-fno-strict-aliasing")
		globals.Add("cc_opts", "-m32")
		globals.Add("cc_opts", "-mfancy-math-387")
		
		# defaults -- normal
		globals.Add("cc_opts", "-fno-exceptions")
		globals.Add("cc_opts", "-c")
		globals.Add("cc_opts", "-Os")
		
	end
	
@end

The main difference is globals.AddOption() vs. globals.Add().. And the Windows version seems to have extra definitions of the function for each platform.
Are there internal changes that are in the optimized version that aren't in the Linux version?

I suggest using the latest source and .bmk files for BMK.
