GCC -V

[wangwen]

Hi,
 
When I type "gcc -V", the report is "gcc: argument 
to `-V' is missing". Should I compiler gcc to get report 
" gcc-x.xx ".
For I am building 
Cygwin hosted Linux toolschain according to the instruction written by Mumit 
Khan( http://www.xraylith.wisc.edu/~khan/software/gnu-win32/ )
 
If I can not get the report report 
" gcc-x.xx ", I will not get the correct result.
 
Please give some hints.
Thanks in advance!
