Fixed compiler warning about redefinition of SIZE_MAX.
Use common.h instead of config.h directly here.
* src/Platform.{h, cc}
The check of ENABLE_NLS is made in gettext.h, so it is not
required
here.
* common.h
2008-02-02 gettextize <bug-gnu-gettext@gnu.org>
Updated gettext related files.
* configure.ac (AC_CONFIG_FILES): Add intl/Makefile.
* configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.17.
