a few glitches in CVS HEAD m4

[Ralf Wildenhues]

Hi there,

This is just a few random observations perusing CVS HEAD m4,
for the benefit of Gary when he returns to work on it.  :)

- I get a build failure of src/getopt.c on GNU/Linux glibc-2.3.2:
| In file included from ../m4/src/getopt.c:80:
| ../m4/src/getopt_int.h:26: error: conflicting types for `_getopt_internal'
| /usr/include/getopt.h:173: error: previous declaration of `_getopt_internal'

Dunno if this is an m4 or a gnulib bug, but getopt.c should not be built
on this system, I believe.  Same issue, more errors, with getopt1.c.
Oh, by the way: config.log:
| configure:16967: checking for getopt.h
| configure:17015: result: yes
| configure:17034: checking for getopt_long_only
| configure:17124: result: yes
| configure:17139: checking whether optreset is declared
| configure:17195: result: no
| configure:17204: checking whether getopt_clip is declared
| configure:17260: result: no
...
| GETOPT_H=''


- A couple of proposed tiny patches:

        * bootstrap (RM): quote default.

This one probably needs a different fix (in libtool?):

        * ltdl/m4/debug.m4 (Xsed): Also define, for
        AC_LIBTOOL_COMPILER_OPTION.
