* acinclude.m4 (LIBVIRT_COMPILE_WARNINGS): Add
-fdiagnostics-show-option.
---
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]
