Re: [PATCH] Support AC_CONFIG_LIBOBJ_DIR

[Paul Eggert]

I like the patch from the Autoconf point of view, assuming the Automake
folks take their bit.  One small point:

"Gary V. Vaughan" <address@hidden> writes:

That would mishandle the case where ac_config_libobj_dir consists
entirely of slashes, or if it contains weird characters like
backslashes or newlines in unusual positions.  Is this possible?  If
so, how about something like this to avoid the problem?

ac_libobj_dir=
test "X${ac_config_libobj_dir-.}" != X. &&
  ac_libobj_dir=`expr "X$ac_config_libobj_dir/" : 'X\(.*[^/]\)' '|' 'X/' : 
'X\(/\)'`
