What compilers do you plan to use? MS C/C++ or cygwin gcc/g++?

[MS MPI is for use with MS compiler only. MPICH binary install is for
MS compilers, and MPICH source install is for cygwin gcc/g++]

Its bad file locks on windows. The only suggestion we have is reboot.

For some cygwin issues - you need to run 'rebaseall' but this doesn;t apper to be
that issue.

If you still have issues - send the complete log [and logfile] to petsc-maint.
