What's the default process stack size in Win32?

==>From the VC2008 docs[1]:

The /STACK option sets the size of the stack in bytes. Use this option only when you build an .exe file.
The reserve value specifies the total stack allocation in virtual 
memory. For x86 and x64 machines, the default stack size is 1 MB. On the 
Itanium chipset, the default size is 4 MB.
commit is subject to interpretation by the operating system. In Windows 
NT and Windows 2000 it specifies the amount of physical memory to 
allocate at a time. Committed virtual memory causes space to be reserved 
in the paging file. A higher commit value saves time when the 
application needs more stack space, but increases the memory 
requirements and possibly the startup time. For x86 and x64 machines, 
the default commit value is 4 KB. On the Itanium chipset, the default 
value is 16 KB.
