* .gitignore: Add lib/ieee754.h. * admin/merge-gnulib (GNULIB_MODULES): Add ieee754-h. * configure.ac: Remove ieee754.h check, as Gnulib now does that. * etc/NEWS: Mention this. * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate. * lib/ieee754.in.h, m4/ieee754-h.m4: New files, from Gnulib. * src/lisp.h (IEEE_FLOATING_POINT): Now a macro so that it can be used in #if. * src/lread.c, src/print.c: Include <ieee754.h> if IEEE_FLOATING_POINT, not if HAVE_IEEE754_H. * src/lread.c (string_to_number): * src/print.c (float_to_string): Process NaNs only on IEEE hosts, and assume <ieee754.h> in that case.
