[Nick Lewycky]

This doesn't work with my llvm-g++ on Linux:;

$ llvm-g++ test/FrontendC++/2009-06-30-ByrefBlock.cpp
test/FrontendC++/2009-06-30-ByrefBlock.cpp: In function 'void fubar()':
test/FrontendC++/2009-06-30-ByrefBlock.cpp:6: error: '__block' was not 
declared in this scope
test/FrontendC++/2009-06-30-ByrefBlock.cpp:6: error: expected `;' before 
'void'
test/FrontendC++/2009-06-30-ByrefBlock.cpp: In function 'void 
__fubar_block_invoke_1(void*)':
test/FrontendC++/2009-06-30-ByrefBlock.cpp:7: error: 'voodoo' was not 
declared in this scope

Should it be marked Apple-only? Or should we fix the Linux llvm-g++ 
build to turn blocks on?
