Subject: Use correct compiler version flag in the autoconf script
X-Git-Tag: v9.17.20~41^2
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=7eb208005fee18735c7ab6b3d05a7e8c2ab516d8;p=thirdparty%2Fbind9.git

Use correct compiler version flag in the autoconf script

The autoconf script prints used compiler version at the end of the
configure script.  Solaris native compiler doesn't support --version,
and -V has to be used which in turn isn't supported by Gcc/Clang.
Detect which version flag has to be used and call $CC with it.
