Re: Error compiling libobjc2 - unwind.h not found

[David Chisnall]

Hi Chris,

It's a private GCC header which, unfortunately, varies a little bit  
between platforms.  I'm a bit surprised it isn't found for you; it has  
been on all of the platforms that I've tried so far, but in some  
uleb128 is defined and in others it isn't.  I plan on removing this  
dependency soon, because the unwind headers just contain copies of the  
functions from the ABI specification (which doesn't seem to stop the  
FSF from slapping a GPL header on them).
