Appears to work fine [using mingw compilers from cygwin with petsc 'stable'].

- install mingw compilers from cygwin setup.exe
- setup PATH to mingw dlls
export PATH=/usr/i686-pc-mingw32/sys-root/mingw/bin/:$PATH

- build PETSc
./configure CC=i686-pc-mingw32-gcc --with-cxx=0 FC=i686-pc-mingw32-gfortran --with-mpi=0 --download-f-blas-lapack=1
make
