I've noticed this flash by before when compiling source distributions rossl on innana~/zope216>python wo_pcgi.py > wo_pcgi.log ./../Components/zlib/zlib.c: In function `PyZlib_compress': ./../Components/zlib/zlib.c:61: warning: assignment from incompatible pointer type rossl on innana~/zope216> fresh zope 2.1.6 source on redhat 6.1/intel. AFAIK it's been there for several releases - I'd never thought to ask... - in the light of the mysterious core dump/thread problem, does this warning matter? -- Dr Ross Lazarus Associate Professor and Sub-Dean for Information Technology Faculty of Medicine, Room 126A, A27, University of Sydney, Camperdown, NSW 2006, Australia Tel: (+61 2) 93514429 Mobile: +61414872482 Fax: (+61 2) 93516646 Email: rossl@med.usyd.edu.au
