commit a03bd1099151e16a07b3a9b3846a28bdef1ba686
Author: Iain Buclaw <ibuclaw@gdcproject.org>

    Check for asprintf and vasprintf during configure stage.
    
    This should fix some build errors seen on AIX, MinGW, and possibly other
    non-GNU systems too due to missing asprintf().
    
    bfd/
    
    	* configure.in: Add asprintf and vasprintf to AC_CHECK_DECLS.
    	* config.in, configure: Regenerate.
