Summary: python.exe 2.4.2 compiled with VS2005 crashes

Initial Comment:
The C runtime library shipped with Visual Studio 2005
performs strict checking of parameters.

In function initsignal() in file
Modules\signalmodule.c, an iteration over all signals
from 1 to NSIG is performed.

The function PyOS_getsig() is called with each of these
integer values. PyOS_getsig() then calls signal() with
the given value which leads to the crash.

According to signal.h from VS2005 only these signals
are allowed:

#define SIGINT          2     
#define SIGILL          4     
#define SIGABRT_COMPAT  6     
#define SIGFPE          8     
#define SIGSEGV         11    
#define SIGTERM         15    
#define SIGBREAK        21    
#define SIGABRT         22    

A solution would be to restrict the loop in
initsignal() to the above values under Windows.

Is VS2005 actually out now then?  This behaviour violates the C standard, 
as far as we can tell, so we when VS2005 was in beta we hoped that they 
would fix it for the final release.

If it is released, though, I guess we need to do something like you suggest 
(along with some colourful comments, I guess).
