I did a pristine checkout of HEAD (already containing the patches in
your email), configured, and attempted to compile.  Here is a very
quick initial report.

First observation:

WINT_MIN and WINT_MAX are undefined.
The Makefile/sed-substitions/stdint.h will substitute both
@BITSIZEOF_WINT_T@ and @SAME_TYPE_WINT_T_LONG@ into an empty strings,
turning this stdint_.h template fragment:

/* wint_t limits */
#ifndef WINT_MIN
#   define WINT_MIN  (-1L << (@BITSIZEOF_WINT_T@ - 1))

into this illegal stdint.h code:

/* wint_t limits */
#ifndef WINT_MIN
# if 0
#  if  > 32 ||                                  <=== flagged error here
#   define WINT_MIN  (-1L << ( - 1))            (<=== silently borked)
#  else

(Three more following places in the "wint_t limits" section are affected
just the same.)

After hacking around this, I get much the same header conflicts as in March.
Here is the error message for md5.c:

Looks to me the issue is still unresolved.
