From Ludolf Holzheid on Bugzilla Bug #2498:
Attached is a patch that adds a configure option to select the file I/O style
on Windows hosts.
It defaults to --enable-win32-io on all windows targets other than Cygwin and
to --disable-win32-io on Cygwin, and thus should be backwards-compatible.
This allows programs using the Unix file I/O style (such as Netpbm's tifftopnm)
to link against libtiff if configured for e.g. MinGW.
