Author: rmacklem Date: Sun Jun 3 19:46:44 2018 New Revision: 334586 URL: https://svnweb.freebsd.org/changeset/base/334586 Log: Fix a gcc8 warning about a write only variable. gcc8 warns that "verf" was set but not used. This was because the code that uses it is disabled via a "#if 0". This patch adds a "#if 0" to the variable's declaration and assignment to get rid of the warning. This way the code could be re-enabled without difficulty.
