Regardless of warnings, after your patch the code that ends up being generated in configure is clearly correct, but I'm a bit confused as to the why. Using check_name_dash would seem the right thing to do here at first sight, especially considering that the same check passed 'qemu-user' (not 'qemu_user') to AC_ARG_WITH() before your recent reorganization - awesome job, by the way! Would you mind spending a couple of minutes pointing out the obvious thing I'm missing? :) -- Andrea Bolognani / Red Hat / Virtualization

It's kind of tricky to dig through the code :) I had to check the autoconf code and the generated configure to figure this out. The thing is that the first argument of AC_ARG_WITH() is placed into *ac_user_opts* variable using with_${first-argument} format. Each option specified for the configure script is for purpose of the "unrecognized options" check renamed using this sed command "sed 's/[-+.]/_/g'" and the renamed option is compared against the *ac_user_opts* variable.
