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.


Cheers,

    Angelo
