Gzilla is a GTK+-based light Web browser, and currently runs only on Unix and Linux platforms. There are no versions supported by Windows platforms. This document describes how the Unix programs of the Gzilla Web browser are ported to Windows. Using the Cygwin environment and the Gzilla source code that was modified by the author, two Windows versions of Gzilla were built: (1) GzillaXW, which was compiled with GTK+, XFree86, Pthreads, Jpeg-6b, Libiconv, and GNU-intl and needs X Server support; (2) GzillaWin, which was compiled with GTK+-Win32, Pthreads, Jpeg-6b, Libiconv, and GNU-intl.
