# This script cannot build windows-x86_64 binaries - only 32-bit support
# is achievable as the 64-bit distribution of e2fsprogs requires a newer
# version of a dll dependency than is available.  The available dependencies
# (version 1.42.7) do not export the ext2fs_close_free function that was
# added to a later version of e2fsprogs (at version 1.42.11), and no early
# enough executable version of e2fsprogs is readily available from Cygwin.
