Failure testing Windows installation

[EdgarChavez]

I'm also having problems testing the installation of GNUstep and gcc on Windows
Vista. What I want to do is program in Objective-C. I have used the Windows
Installer (http://www.gnustep.org/experience/Windows.html) and installed, in 
order: 

1.  GNUstep system 0.23.0
2.  GNUstep core   0.23.1
3.  GNUstep devel  1.0.0

All three packages installed successfully.  I have been following the
instructions entitled "Installing and using GNUstep and Objective-C on Windows"
shown here: 
http://www.techotopia.com/index.php/Installing_and_using_GNUstep_and_Objective-C_on_Windows

The installation appears to be successful.  I can get a command window with the
MinGW shell. I have copied and saved the sample program hello.m.  When I try to
execute the command those instructions suggest, i.e.:

$ gcc `gnustep-config --objc-flags` -L /GNUstep/System/Library/Libraries hello.m
-o hello -lgnustep-base 
-lobjc

I get the message:  
gcc.exe: gnustep-config --objc-flags: No such file or directory
hello.m:1:34: Foundation/Foundation.h:  No such file or directory

I can find the file gnustep-config in the following folder:

c:/GNUstep/GNUstep/System/Tools/gnustep-config

I have tried many things. From the directory in the previous line I ran:

gnustgep-config --objc-flags -I/home/Anne/GNUstep/Library/Headers

Now, from c:/GNUstep/GNUstep/home/Anne, where hello.m is located, I try:

gcc hello.m -o hello

and I get messages that begin:

hello.m:1:34: Foundation/Foundation.h: No such file or directory

What should I do?  Any help would be extremely welcome.  Thanks,
