I have recently downloaded the 'proposed' package of MinGW and am currently trying to run it on my Windows XP machine along with the msys package.  I am using the Visual-MinGW IDE too (v0.56).  I can compile and run the sample programs provided in the Visual-MinGW release, but I have been having one peculiar problem: I get compile errors when I try to include the <iostream> header file (or any of the C++ header files for that matter).  I try to include the path to that directory with the lines:
-I c:\msys\1.0\mingw\include\c++\3.4.2
I have also used the -I- option as well as the -Isystem option, but to no avail. 
One thing I noticed that might have mattered: when I built the winui project in the visual-mingw download (like they said to do in the installation guide), it failed to copy one file to the mingw\include directory, and that was the "libwinuid.a" file, which was not even in the Visual-Ming project directory.  It did copy the libwinui.a file into the mingw\lib director.
Here's the install.bat file that Visual-MIngw used to do that file copy:
    del install.log
    xcopy lib\libwinui.a C:\Msys\1.0\mingw\lib >> install.log
    xcopy libdebug\libwinuid.a C:\Msys\1.0\mingw\lib >> install.log
    xcopy /S wui\*.h C:\Msys\1.0\mingw\include\wui >> install.log
The first file was copied. The second file was not copied, since it wasn't even there.  No wui*.h files were copied.  Is there a way I can get these files directly and put them in there? Would that help?
sample program used:
    #include <stdio.h>
    #include <iostream>
     int main() {
     return 0;
log of the build:
    Building makefile...
    Make clean...
    unlink .\test.o
    Build all...
    gcc -Iinclude -Ilib -g -W -Wall   -c .\test.c -o .\test.o
    .\test.c:2:20: iostream: No such file or directory
    .\test.c:7:2: warning: no newline at end of file    
The command 'gcc' appears to be automatic to the IDE when I hit "build all".  I had the language setting on C++ too.

The warning, "no newline at end of file", is not persistent like the iostream error.
Does anyone have any ideas as to what this could be?  winui version that I am running is 3.8.
I would greatly appreciate any help here.  I would like to get this compiler up and working to work on some projects I have.  So far it seems like a nice little compiler to run and learn on, if I can get it to work.
With much thanks,
David Starkweather.
