w32reg.c string search termination

[Saalmann, Harald]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.
 
Your bug report will be posted to the address@hidden mailing
list.
 
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
 

In file src/w32reg.c, line 35: The directive
   #define SYSTEM_DEFAULT_RESOURCES  ...
doesn't close the string literal with two adjacent NUL characters,
which is needed by function w32_get_rdb_resource() called from line
142 to terminate the string lookup correctly.  
(It is unlikely that this ever triggered any noticeable bad behavor.)
 
[Appending a "\0" will probably do it.  I haven't tested anything, 
because I don't run Windoze on my own machines, and on this one I even
have to use M$ Outlock to ship this mail out...]
 

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
d:/Program_Files/ntemacs22/etc/DEBUG for instructions.
