 GNU sed
 
 I was trying to configure sed-4.0.5 on Solaris 2.6 using CONFIG_SHELL=/bin/ksh.
 >Description:
 During configure when config/missing is invoked as
   config/missing --run makeinfo --help
 It decides that '--help' is a file to scan for "@setfilename" and then decides 
the output of "sed -n '...' --help" is a (list of) filenames to touch.
 
 [I don't know if the "Category" of this PR should be "autoconf" or "config".]
 >How-To-Repeat:
 Try to configure, e.g. sed-4.0.5, when there is no makeinfo and the sed 
already on the path is GNU sed.  A bunch of arbitrary files are created as if
     touch `sed --help`
 In the sed-4.0.5 case this includes a file 'sed' which prevents configure from 
completing sucessfully.
 >Fix:
 Ignore arguments starting with '-' in the makeinfo emulation of 
config/missing.  E.g.
