I'm not exactly sure what you're asking... I looked around a bit, and other projects seem to respond to -Wcast-align warnings with everything from disabling the warnings to fixing their code. If you're asking what the rationale of -Wcast-align is, I found two great texts: <https://www.securecoding.cert.org/confluence/display/seccode/EXP36-C.+Do+not+convert+pointers+into+more+strictly+aligned+pointer+types> <http://mail-index.netbsd.org/tech-kern/2003/08/11/0001.html> But, like I said in my first post, for the moment anyway, I'm not interested in trying to get all of libusbx to build cleanly with -Wcast-align. Would you accept a patch with my solution #1, again: 1) making libusb_control_transfer_get_setup not inline, so it's iffy cast is hidden in a .c file Cheers, -- ____________________________________________________________ Sean McBride, B.
