I have the follwing patch to get the conditionals required for windows.

PETSC_CYGWIN_BROKEN_PIPE is now required only for 'cygwin-ar' - so
thats the first change.

And then the ARCHIVE_RECIPE_WIN32FE_LIB is required only when 'win32fe
lib' is the archiver. [In the future there could be others?]

Instead of adding configure tests for these - I just added conditionals in the gmakefile.
