You might benefit from searching the DJGPP mail/newsgroup archives. 
Problems similar to what you describe have been reported before.  The main
reason to get these messages was a faulty libgcc.a, so first check if your
copy of libgcc.a defines __pure_virtual.  If it does (and I guess it does,
because you say you have this problem with both v1.12m4 and v2, but *do* 
check), then point your favorite Web browser to this URL: 

	http://www.delorie.com/djgpp/mail-archives/

and search the archives for ``__pure_virtual''.  Most likely, you'll find 
the reason for your trouble in a matter of seconds.
