X-Received-From: 66.165.176.89 Subject: [Qemu-devel] [PATCH 09/12] configure: do_compiler: Dump some extra info under bash X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Juergen Gross , Janosch Frank , Thomas Huth , Stefano Stabellini , Peter Maydell , "Kent R.

The information may be lacking in other shells, resulting in harmless empty output. (This is why we don't use the proper ${FUNCNAME[*]} array syntax - other shells will choke on that.) The extra output is only printed if configure is run with bash. On systems where /bin/sh is not bash, it is necessary to say bash ./configure to get the extra debug info in the log.
