- * iconvme.c (SIZE_MAX): New macro, if not already defined.
- (iconv_string): Don't guess a size-zero buffer, as that might cause
- buffer overrun. Instead, avoid multiplying by MB_LEN_MAX if the
- result would be 'too large', where 'too large' is (heuristically)
- the square root of SIZE_MAX, divided by MB_LEN_MAX to allay
- overflow concerns. This will prevent some unwanted malloc failures
- when the inputs are very large.

- * iconvme.h: New file, extracted from toutf8.c but improved.
- * iconvme.c: New file.
- * toutf8.c: Include stringprep.h first, to make the compiler check
- that stringprep.h is standalone. Improve comments. Replace
- #include of errno.h and sys/param.h with iconvme.h. Don't define
- ICONV_CONST.
- (stringprep_convert): Rewrite to use iconvme.h.
- * Makefile (libcidn-routines): Add iconvme.
