I've been trying to compile sparse on win32 to no avail. I tried both mingw32 with pre-built ATLAS and LAPACK and Cygwin, both with the Scipy CVS. Both setups work OK (well, cluster also fails on Cygwin, but I took it out), and they crash more-or-less with the same error ("parse error before numeric constant", below). Extensive Googling shows that this means a numeric constant is already used somewhere else, but I got no solution to work around it... Ideas?
