# Caveats:
# 0) Only Fedora is supported as a cross-compilation environment
# 1) Install all mingw packages and wine; start a random wine app
#    to ensure you have ~/.wine/drive_c
# 2) cp -R /usr/i686-pc-mingw32/sys-root/mingw/ ~/.wine/drive_c/mingw
# 3) Configure gst as follows:
#   ../configure \
#      --host=i686-pc-mingw32 \
#      --prefix=/nonexistent \
#      --exec-prefix=/nonexistent \
#      --bindir=/nonexistent \
#      --datarootdir=/nonexistent \
#      --with-imagedir=/nonexistent/image \
#      --with-moduledir=/nonexistent/modules \
#      --disable-glibtest \
#      --disable-gtktest \
#      LDFLAGS=-L/usr/i686-pc-mingw32/sys-root/mingw/lib/
# 4) Run ./makesetup
