  New Revision: 61326

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=61326

  Log:
    Support C89 if possible
    
    * addr2line.c: Because stdbool.h is a C99 feature, compile error
      occurs with some old compilers without specifying C99 options.
      Fix compile error with Oracle Solaris Studio 12.4 on Solaris 10.
      [Bug #14200] [ruby-dev:50366]
    
    * missing/stdbool.h: Alternative of stdbool.h for C89 compilers.

  Added files:
    trunk/missing/stdbool.h
  Modified files:
    trunk/addr2line.c
Index: addr2line.c
