Comment:

 There was no response to my mailing list post so I'm going ahead with the
 change.

 Upstream switched to using ppc7400 as part of this megacommit:

 https://github.com/libffi/libffi/commit/0e5843995f46900ef212531281e08b224464f413

 But the comments in the ChangeLog show that the intention was to provide
 64-bit support. There's no mention in the comments about also switching
 the 32-bit support to require G4, so the change may have been
 unintentional or upstream may simply not have considered that people using
 pre-G4 processors might still be interested in libffi.

 On Mac OS X 10.5, if you compile for arch ppc, gcc silently substitutes
 arch ppc7400 since 10.5 requires a G4 or better, so this won't make a
 difference for Leopard systems, so I'm only increasing the revision of the
 port for Tiger.

 Compiling for G3 should be fine for a G4, it just won't include any
 G4-specific optimizations. For PowerPC, MacPorts always compiles with arch
 ppc, not arch ppc7400, so this change makes libffi consistent with other
 ports.
