Main.log from build on Tiger with PowerPC 7447A

The issue here seems to be that /usr/include/stdint.h on Tiger does not define __WORDSIZE, whereas all newer versions of that header do declare it.

For right now, you should be able to get away with defining it manually, like this in the Portfile:

configure.cppflags-append -D__WORDSIZE=32

for a permanent fix, this is another one that should best go in the legacy-support PG, as a rider on stdint.h and then it will be fixed for all ports, forever. I'll look into that.

Worked here, too!
