While attempting to build with Windows SDK for Windows 7 (7.1), 7.1.7600.0.30514 I get the following error:

Category should have been set to "build" but redmine doesn't allow me to switch it now. Relevant to both 2.0.0 and 1.9.3.

From the log, I noticed the line #188 of configure.bat
echo>>confargs.c !ifndef CONFIGURE_ARGS

output "ifndef CONFIGURE_ARGS" without "!" for some reason.

I guess this issue is related with the V option of CMD.EXE.
According to the help message:

/V:ON Enable delayed environment variable expansion using ! as the
delimiter. For example, /V:ON would allow !var! to expand the
variable var at execution time. The var syntax expands variables
at input time, which is quite a different thing when inside of a FOR
loop.

Here is a test case

C:\Tmp>type a.bat
@echo off
echo !ifndef CONFIGURE_ARGS

C:\Tmp>cmd /v:on
Microsoft Windows [Version 6.1.7601]

C:\Tmp>a.bat
ifndef CONFIGURE_ARGS

C:\Tmp>cmd /v:off
Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation. All rights reserved.

C:\Tmp>a.bat
!ifndef CONFIGURE_ARGS

In order to workaround this issue, you can use "setlocal DISABLEDELAYEDEXPANSION" in front of batch file.
C:\Tmp>type a.bat
@echo off
@setlocal DISABLEDELAYEDEXPANSION
echo !ifndef CONFIGURE_ARGS

C:\Tmp>cmd /v:on
Microsoft Windows [Version 6.1.7601]

C:\Tmp>a.bat
!ifndef CONFIGURE_ARGS

C:\Tmp>cmd /v:off

C:\Tmp>a.bat
!ifndef CONFIGURE_ARGS

Very nice. I checked the shortcut I use to launch a shell and found the "Target:" had

C:\Windows\System32\cmd.exe /E:ON /V:ON /T:0E /K "C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\SetEnv.Cmd" /x86 /release /win7

After changing to /V:OFF I get the following and am off and running again.

C:\Users\Jon\Documents\RubyDev\ruby-git\build>..\win32\configure.bat --prefix=c:\projects\ruby193-mswin --target=i686-mswin32 --disable-install-doc --disable-win95
Creating Makefile.new
PROCESSOR_LEVEL =
type `nmake' to make ruby.

Normally this is where I'd suck it up and eat a little plate of steaming crow for not configuring my system correctly by saying something like "Sorry for the noise, please close".

But seems to be one of those tweaky issues we should make disappear. Is there a way to make configure.bat immune to /V:ON or /V:OFF in this case, perhaps by adding your @setlocal DISABLEDELAYEDEXPANSION workaround? Would it then cause problems for those using the IDE to build?

If the workaround isn't solid, I'd like to see this issue documented in win32/README.win32

Thank you reporting, Jon.
And, thank you debugging, Heesob.

Thank you both as this was fantastically easy. Onto learning how to covert optflags and debugflags options into cl options.
