Hi,

I upgraded to the new binutils version and I now get autoimport errors as
below. We have had this problem already a long time with MinGW, there the
report is
https://sourceforge.net/tracker/?func=detail&aid=683455&group_id=2435&atid=1
02435. 

The code is visible at
http://cvs.doc.wustl.edu/cvsweb.cgi/ACE_wrappers/ace/Time_Value.h?rev=4.31&c
ontent-type=text/x-cvsweb-markup

The hack at the end of the file for MinGW is workable now for Cygwin also. 

It is a hard one to reproduce, it only happens in when the class is used in
nested templates. See the mingw report for more info
