configure quotes problem under Tru64 unix

[Nicolas Joly]

Hi,

I just found a small problem with CVS autoconf under Tru64 unix.

address@hidden [temp/autoconf]> ./configure 
./configure: $/d confdefs.h
      echo
    fi
    test "$ac_signal" != 0 &&
      echo "$as_me: caught signal $ac_signal"
    echo "$as_me: exit $exit_status"
  } >&5
  rm -rf conftest* confdefs* core core.* *.core conf$$* $ac_clean_files &&
    exit $exit_status
    : not found
checking for a BSD compatible install... config/install-sh -c
checking whether build environment is sane... yes
checking for mawk... no
checking for gawk... no
checking for nawk... nawk
checking whether make sets ${MAKE}... yes
[...]

This problem is located in `lib/autoconf/general.m4' :

# When interrupted or exit'd, cleanup temporary files, and complete
# config.log.  We remove comments because anyway the quotes in there
# would cause problems or look ugly.
trap 'exit_status=$?
  # Save into config.log some information that might help in debugging.
  {
    echo
    AS_BOX([Cache variables.])
    echo
[...]
    if test -s confdefs.h; then
      AS_BOX([confdefs.h.])
      echo
      sed '/^$/d' confdefs.h
      echo
    fi
  } >&AS_MESSAGE_LOG_FD
  rm -rf conftest* confdefs* core core.* *.core conf$[$]* $ac_clean_files &&
    exit $exit_status
     ' 0

The `trap' and `sed' quotes conflicts with Tru64 `/bin/sh' (but it
seems to work fine with both ksh and zsh). Using double quotes for the
`sed' call solves the problem.

Thanks in advance.
