Re: Error compiling libobjc2 - unwind.h not found

[David Chisnall]

Ah, well spotted.  I've fixed that now.  Libobjc was originally  
intended to be built as part of gcc (modularity is not something that  
gcc team are big fans of) and so used "unwind.h" to make sure it  
picked up the version of the header provided by GCC, not the one  
provided by the system, which is the exact opposite of what we want.
