I have Windows 2000 SP4 with an up-to-date, reasonably complete Cygwin environment (cygwin 1.5.5-1, gcc 3.3.1-3, etc). I use the usual "./configure, make" process. The build fails to produce executables, with output like this

So I presume that the problem is caused by the installation of a newer version of some Cygwin software component in the meantime.

Well, if it worked before but doesn't now, something has certainly 
changed.  However, presumptions beyond that aren't too helpful.  I'd 
suggest figuring out who's looking for this symbol and where it should
come from.  Track it from there until you find the library you're 
missing.
