commit 9996695f88b19a48bd8d50b84f85509b8626fb01
Author: Andy Wingo <address@hidden>

    Require C99 to build Guile.
    
    * configure.ac: Require C99 or later.  Emacs does, therefore so can
      we.  Note that by default GCC compiles in "gnu11" mode these days, and
      this declaration doesn't change that.
