ieee754-h: new module It looks like Emacs can use this for some NaN processing. Emacs uses it only on double NaNs so it should be safe. * MODULES.html.sh (func_all_modules): Add ieee754-h. * config/srclist.txt: Mention ieee754.h in a comment. * doc/glibc-headers/ieee754.texi (ieee754.h): Gnulib now has a substitute that should work except for long double and for non-IEEE platforms. * lib/ieee754.in.h, m4/ieee754-h.m4, modules/ieee754-h: * modules/ieee754-h-tests, tests/test-ieee754-h.c: New files.
