I've compiled a 64-bit version of the existing cabextract 1.4-1 package: http://www.cabextract.org.uk/cygwin64/cabextract-1.4-1.tar.bz2 http://www.cabextract.org.uk/cygwin64/cabextract-1.4-1-src.tar.bz2 Other than the architecture, there are no differences between this and the existing 32-bit version.
