[ryandesign (Ryan Carsten Schmidt)]

Same on Tiger i386. apple-gcc42-devel will build, but is at present not the drop-in replacement for apple-gcc42 that it should be; see #24759

[ryandesign (Ryan Carsten Schmidt)]

Same on Snow Leopard; see duplicate #22115. I doubt this port installs on any version of Mac OS X ever since the -arch flag was added to MacPorts in 1.8.0.

Clearing archflags as of r70042.
