I see.  I wanted to examine how llvm-gcc-4.2 and mainline handle the testcase
2007-10-17-SJLJExceptions.m, but it doesn't compile with either:

$ gcc-4.2 -x objective-c 2007-10-17-SJLJExceptions.m -O2 -fexceptions -S -o -
        .file   "2007-10-17-SJLJExceptions.m"
2007-10-17-SJLJExceptions.m:3:34: error: Foundation/Foundation.h: No such file or directory
2007-10-17-SJLJExceptions.m:5: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘*’ token
2007-10-17-SJLJExceptions.m:7: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘bork’

Ciao,

Duncan.

PS: the run line has "-arch i386".  Is that right?  My compiler doesn't recognize it.
