	* bootstrap: Update the time stamp of reference output files to
	avoid them to be illegitimately regenerated when checked out from
	the repository.

	* configure.ac:
	Check <sys/int_limits.h> presence.
	* src/stdint_.h:
	Use <sys/int_limits.h> when it is present to define limit macros.
	A problem occured on our SunOS: <stdint_.h> includes <sys/int_limits.h>
	through several files, leading to a macro definition clash.

from  Benoît Perrot  <benoit@lrde.epita.fr>

	* configure.ac:
	Check isblank presence.
	* src/shell/shell.hh, src/shell/shell.cc:
	Provide isblank when the platform lack it.

from  Benoît Perrot  <benoit@lrde.epita.fr>

	* src/vm/cpu.cc:
	Effectively use Cpu::register_type, and not system's register_t.
	cpu.cc did not compile on SunOS, where register_t is not defined.

from  Benoît Perrot  <benoit@lrde.epita.fr>

	* config/stdint.m4, config/inttypes.m4:
	GNUlib's <stdint.h>/<inttypes.h> detection tools.
	* configure.ac:
	Use gl_HAVE_STDINT_H to check <stdint.h>/<inttypes.h> presence.
	Define __STDC_LIMIT_MACROS to access to some macros that 
	the ISO C99 standard specifies to be explicitly requested 
	in C++ implementation.
	* src/stdint_.h:
	GNUlib's "ISO C 99 <stdint.h> for platforms that lack it."
	* src/Makefile.am:
	Generate stdint.h from stdint_.h on platforms that lack it.

	* src/vm/cpu.hh, src/vm/memory.hh, src/inst/data_section.hh:
	Include config.h to get information on <stdint.h>/<inttypes.h>
	presence.

        The problem appeared on NetBSD.

        Fix problem with case-insensitive filesystems.

        * distrib/debian/changelog: Rename as...
        * distrib/debian/changelog-deb: ...this.
        * distrib/debian/Makefile.am: Adjust.

        * bootstrap.sh: Stop at first error (sh -e).
        Don't use "cd -" because it does not work with BSD's /bin/sh.
