Hi Adam,

The functions 'regcomp', 'regexec' and 'regfree' are part of glibc on
Linux environments. As Win32 doesn't have glibc you need to use a
separate library like mingw32-libgnurx for these functions. This package
should be available in the Fedora 10 repositories. You may need to patch
some files (configure.ac/Makefile.am) in libvirt to get it to use
mingw32-libgnurx (you need to add '-lregex' to the LDFLAGS).
