I've already added my change to balay/testharness-wPETSC_DIR - and merged to next.

Its defined in both the 'if' and 'else' blocks - so defined on all builds.

For eg:
linux: http://ftp.mcs.anl.gov/pub/petsc/nightlylogs/archive/2017/01/17/configure_master_arch-cuda-double_es.log
wPETSC_DIR = /sandbox/petsc/petsc.clone
Windows: http://ftp.mcs.anl.gov/pub/petsc/nightlylogs/archive/2017/01/17/configure_master_arch-mswin-intel_ps4.log
wPETSC_DIR = C:/cygwin64/home/petsc/petsc.clone-2

We need this mapping so that 'ex10 -f ${wPETSC_DIR}' works with both linux and windows binaries.
