use the lib name "intl" on windows
only build a static libffi for now
convert spaces to tabs, make sure glib's configure picks up zlib when trying -lz
use clwrapper.py on msys for glib, make sure the zlib flags are picked up
clean up some indentation, only add flags for libs that have been built already
add zlib to defs, export lib specific flags even if it isn't 'enabled' yet
add libffi to defs, add it as a default target for msys
