Here's an example of how things change, when using './configure
--enable-compiler-warnings=error' and introducing something gcc
would warn about:
CC libvirt_driver_nwfilter_la-nwfilter_ebiptables_driver.lo
cc1: warnings being treated as errors
nwfilter/nwfilter_ebiptables_driver.c: In function
'_iptablesCreateRuleInstance':
nwfilter/nwfilter_ebiptables_driver.c:1059: error: unused variable 'oops'
[-Wunused-variable]
Looks fine to me.
Thanks for splitting the long line and fixing the m4 quoting, too.
