[B2-devel] "Carbon Pasteboard is unavailable under 10.6"

[C.W. B. <com...@ho...>]

When compiling either SheepShaver or Basilisk II, I get the following warning when compiling for either 32 and 64-bit:
"Carbon Pasteboard is unavailable under 10.6"
To my knowledge, the Carbon Pasteboard is available under 10.6 on 32-bit, but many high-level GUI code (like the Carbon Pasteboard) aren't present on 64-bit.  Perhaps a better test would be to check for __LP64__ and not build if it's there, instead of checking for 10.6.
