You'll need the following patch to get petsc working with cygwin64/gcc [configure and build with this patch] https://bitbucket.org/petsc/petsc/commits/e4773d96ef73f1e0b315c5b0194cae499d71e207 Sr you can edit PETSC_ARCH/include/petscconf.h and remove the flag PETSC_HAVE_FENV_H and rebuild the libraries.
