Re: Question about g++


One other thing I just thought about.  You might check your
/usr/lib/libc.a.  Mine is a soft link to /usr/lib/libcygwin.a

commpg@CSU6220509A /usr/lib
$ ls -al libc.a
lrw-r--r--   1 commpg   None           22 Mar  9 15:22 libc.a -> libcygwin.a

If that's not the problem, then you have gone beyond my 
ability to help (Without more research on my part, requiring
more time).
