The first patch was discussed here: http://thread.gmane.org/gmane.comp.emulators.libvirt/6353
What are the c-ctype functions and where do they come from ? I'm guessing from the description, they're variants of ctype functions which are guarenteed to operate in the C/USASCII locale, regardless of LANG setting. Are they from gnulib ?
