Log message:
Add a better set of 64-bit fixes that both satisfy make test
and math/lapack build. This new patch-ai is from debian.

Log message:
Remove the patch-ai which used to fix 64-bit types in f2c.h.
Now it breaks stuff on amd64 instead, notably math/lapack.
NB: This change makes "make test" fail for this package on amd64.
On the other hand, math/fftw (which uses lapack) test suite succeeds.
Maybe tests here are simply broken ...

Bump revision and bl3 dependency.
