There are a few causes which might be involved, but the usual one is that
you have an old version of libgcc.a which doesn't include this symbol. 
You can check if it includes it with the `nm' program which should be in
your bin/ subdirectory.  The DJGPP FAQ list explains in section 8.9 how to
use `nm' for this purpose (there is also a chapter on `nm' in the binutils
docs).
