Right, I figured something like that can be happening but not how to fix 
it.

However, I have tested succesfully the following patch for Linux:

pearu at p4:~/svn/scipy/Lib/special$ svn diff
Index: setup.py
===================================================================
--- setup.py    (revision 1491)
+++ setup.py    (working copy)
@@ -12,6 +12,8 @@
  #        define_macros.append(('NOINFINITIES',None))
  #        define_macros.append(('NONANS',None))

+    # Force using cephes round.
+    define_macros.append(('round','cephes_round'))

      # C libraries
      config.add_library('c_misc',sources=[join('c_misc','*.c')])

Could someone on OS X and Windows systems test if the patch works on these 
platforms as well?

Thanks,
Pearu
