 does return

Hi Rudolph,

> bfd.c: In function `_bfd_abort':
> bfd.c:796: warning: `noreturn' function does return

This looks like it may be a problem with your system header files.  The 
_bfd_abort() function ends with a call to the system function _exit() 
which should not return.  Hence _bfd_abort() does not return.  It would 
appear from this error message that the system header file which 
declares the prototype for _exit() on your system (probably unistd.h) 
does not include the "__attribute__ ((noreturn))" qualifier.

The proper solution to this problem would probably involve complicated 
configuration scripting to detect the missing attribute in the system 
header and change the prototypes of various bfd functions accordingly. 
Since that is likely to introduce its own set of bugs however, please 
could you try the uploaded alternative patch which just adds a local 
prototype for _exit() to the _bfd_abort() function.

Cheers
   Nick
