[libvirt PATCH v2 22/56] configure: request system specific extensions

Posted by Daniel P. Berrangé 6 years ago

The AC_USE_SYSTEM_EXTENSIONS macro causes things like
"USE_GNU" to be defined, which enables access to OS
specific extensions to POSIX. We currently got this
indirectly via GNULIB's 'extensions' module which is
a dependancy of other GNULIB modules we use.
