problems with lilypond 2.5.31 under WinME

[Brynne and Russ Jorgensen]

When I run lilypond from the desktop, it does not start up lilypad with 
the Welcome_to_LilyPond.ly file.  However, if I start a command shell, 
cd to the LilyPond usr\bin directory and then run lilypond, it DOES 
start up lilypad.  I thought it was a problem quoting spaces in the 
install directory, so I uninstalled and re-installed in a directory 
without spaces, and it's still not working.  I dug a little deeper, and 
I think now that the problem is that lilypond.exe is not affecting the 
environment at all.  I put the following batch file in c:\windows to see 
what lilypond.exe does to the environment:

==== c:\windows\lilypad.bat ====
@echo off
set > d:\tmp\debug.txt

and after I run lilypond from the desktop, the d:\tmp\debug.txt contents 
are as follows:

COMSPEC=C:\WINDOWS\COMMAND.COM
PATH=C:\WINDOWS;C:\WINDOWS\COMMAND;D:\CYGWIN\HOME\RBJ\VIM\VIM61;D:\CYGWIN\BIN;d:\PGP;d:\infozip\unz550;d:\infozip\zip23;D:\PROGRA~1\VPN603
PROMPT=$p$g
TEMP=D:\TMP
TMP=D:\TMP
VIM=D:\cygwin\home\rbj\vim
VIMINIT=source D:\cygwin\home\rbj\.vimrc
TDIR=D:\TMP
winbootdir=C:\WINDOWS
windir=C:\WINDOWS
BLASTER=A220 I2 D3 T4

As you can see, PATH does not contain lilypond\usr\bin, and the various 
GS_FONTPATH, GS_LIB, GUILE_LOAD_PATH and PANGO_RC_FILE environment 
variables aren't set at all!  It looks like setup_paths() is supposed to 
be doing this, but it doesn't appear to be working.  Therefore, whenever 
lilypond tries to execute a program that it should find in its path 
(lilypad.exe and more importantly also gs.exe), the program isn't found. 
 I can't get lilypond.exe to compile, so I can't debug any deeper.  Let 
me know if you have some things you'd like me to try...
