+ Assume freestanding C89 headers, string.h, stdlib.h.
+ * data.c, doprnt.c, floatfns.c, print.c:
+ Include float.h unconditionally.
+ * gmalloc.c: Assume C89-at-least behavior for preprocessor,
+ limits.h, stddef.h, string.h. Use memset instead of 'flood'.
+ * regex.c: Likewise for stddef.h, string.h.
+ (ISASCII): Remove; can assume it returns 1 now. All uses removed.
+ * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
+ * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
+ (STDC_HEADERS): Remove obsolete defines.
