It is known problem. There are 2 possible solutions:

	- use gcc command line option -frepo (should work with Your
          installation). 

	- use binutils that supports weak symbols. Unfortunatelly none
          of official ports in DJGPP distribution does it. If You're
          really brave enough You can try recent binutils snapshots
          (I put precompiled binaries of 8 February snapshot at
	  http://www.lanet.lv/~pavenis/djgpp/bnu-000208.zip). NOTE once 
	  more: it's development version, it can crash, do other
          weird things, etc. Well that didn't happen to me. Also
	  You should use command line line option -mbnu210 to enable 
          gcc to use extra features of binutils snapshots (if this option
	  doesn't work, make sure You have latest update of gcc2952b.zip
	  and gpp2952b.zip)
