This made (string-to-number "10") 20% faster on my old desktop, an AMD Phenom II X4 910e running Fedora 25 x86-64. * admin/merge-gnulib (GNULIB_MODULES): Remove strtoumax. * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate. * lib/strtoul.c, lib/strtoull.c, lib/strtoumax.c, m4/strtoull.m4: * m4/strtoumax.m4: Remove. * src/editfns.c (str2num): New function. (styled_format): Use it instead of strtoumax. Use ptrdiff_t instead of uintmax_t. Check for integer overflow. * src/lread.c (LEAD_INT, DOT_CHAR, TRAIL_INT, E_EXP): Move to private scope and make them enums. (string_to_number): Compute integer value directly during first pass instead of revisiting it with strtoumax later.
