--- Comment #13 from David Edelsohn <dje at gcc dot gnu.org> --- The GCC build process has requirements, including SVR4/POSIX awk. GCC works on a wide variety of systems, but needs to have a base set of requirements and limit accommodation to prevent things from getting out of control. Building and installing Gawk or Nawk or another implementation is not an unreasonable burden.
