* Makefile.in (AUTOCONF_INPUTS): New macro.
($(srcdir)/configure, $(srcdir)/src/stamp-h.in): Depend on it,
so that these files also depend on m4/getopt.m4.
* configure.in: Configure getopt by including m4/getopt.m4,
and configuring a getopt replacement if necessary.
* make-dist: Add m4 subdirectory. Unlink lib-src/getopt.h.
* m4/getopt.m4: New file.
* lib-src/Makefile.in (mostlyclean): Remove getopt.h, getopt.h-t.
(GETOPT_H): New macro, from gnulib.
(getopt.h): New rule, from gnulib.
(GETOPTOBJS): Now autoconfigured.
(GETOPTDEPS): getopt.h is now autoconfigured.
(getopt.o, getopt1.o): Depend on $(GETOPT_H), not ${srcdir}/getopt.h.
(getopt.o): Depend on ${srcdir}/gettext.h.
(movemail.o): Depend on $(GETOPT_H).
* lib-src/getopt.c, lib-src/getopt1.c: Sync from gnulib.
* lib-src/getopt_.h, lib-src/getopt_int.h, lib-src/gettext.h:
New files, from gnulib.
* lib-src/getopt.h: Removed (now is getopt_.h).
* nt/inc/gettext.h: Remove; no longer needed now that
lib-src/gettext.h exists.
* src/s/cygwin.h (C_SWITCH_SYSTEM): Remove, since gettext.h is
now part of lib-src.
changes. Add a pointer to another site with detailed configure
and build instructions. Suggest to look at config.log when
configure fails. Add MinGW Make 3.80 to the list of successful
combinations.
Delete config.log before doing anything else.
Write additional diagnostics to config.log in case of failures to
compile test programs, including the failed test program itself.
Add a test for support of -mtune=pentium4 switch to GCC; if it is
supported, set up MCPU_FLAG variable on the various Makefiles to
use that switch during compilations. (This avoids GCC warning
about -mcpu being deprecated.)
`verbose' arg to COPY_CHUNK only if DEBUG_DUMP is defined in the
environment. Print section names with %.8s.
(COPY_CHUNK): New 4th arg `verbose'; print diagnostic messages
only if non-zero. All callers changed.
