  New Revision: 60843

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=60843

  Log:
    addr2line.c: fix r60841 for glibc before 2.22
    
    SHF_COMPRESSED was not defined until glibc 2.22, and there are
    older distros (e.g. Debian 8.x jessie) which do not have this
    defined.
    
    Perhaps it is safe to define SHF_COMPRESSED to (1 << 11) ourselves,
    too, since ELF should be a standardized format.

  Modified files:
    trunk/addr2line.c
