Fix a gcc8 warning about a write only variable.

Browse Source 
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.
