Usually I build ROOT (a Cern application) under Cygwin and this was done also a few day ago (with cygwin 1.5.19-4 and with the snapshots before 20060227).
Now with the snapshot 20060227 the build fails with: undefined reference to '___isnand' I have noted that with this snapshot, math.h declares extern '__isnand'. If it is extern, where is it defined? Are these things related to the post: <http://cygwin.com/ml/cygwin/2006-02/msg00968.html> and its replies? Reinstalling cygwin 1.5.19-4 or the snap 20060224 the build of ROOT is fine.
