Install of xchat-2.8.4-1.exe
(http://www.silverex.org/download/xchat-2.8.4-1.exe ) fails due to a quote
Problem between CreateProcessW and libs/wine/loader.c:

Still correct:
0040:trace:process:CreateProcessW app (null) cmdline
L""C:\windows\system32\cmd.exe" /C
""C:\windows\temp\is-TNQIK.tmp\update-modules.bat"
"C:\Programme\X-Chat 2\lib\pango-querymodules.exe"
"C:\Programme\X-Chat 2\etc\pango\pango.modules"""

Broken in cmd.exe:
001c:trace:cmd:wmain /c command line:
'L""C:\windows\temp\is-TNQIK.tmp\update-modules.bat
C:\Programme\X-Chat" "2\lib\pango-querymodules.exe
C:\Programme\X-Chat" 2\etc\pango\pango.modules"'

the update-modules is really simple:
--- cut ---

%1 > %2
