I've been using numarray 0.8 since 0.9 has some bugs that I can't easily work around. Since these have been fixed in CVS, I finally decided to try to download and compile a copy of numarray from CVS. Unfortunately, 'python setup.py build' bombs out almost imediately: creating build\temp.win32-2.3 creating build\temp.win32-2.3\Release creating build\temp.win32-2.3\Release\Src C:\Program Files\Microsoft Visual Studio\VC98\BIN\cl.exe /c /nologo /Ox /MD /W3 /GX /DNDEBUG -IInclude/numarray -IC:\python23\include -IC:\python23\PC /TcSrc\_convmodule.c /Fobuild\temp.win32-2.3\Release\Src\_convmodule.obj_convmodule.c Src\_convmodule.c(683) : warning C4244: '=' : conversion from 'int ' to 'float ', possible loss of data ....

Any hints as to what I could to make this work? I downloaded the source for version 0.9 and tried compiling it but got the same set of errors. Alternatively, is there going to be a 0.9.1 or 0.10 release soon? Thanks, -tim
