The part of my story you snipped in the ellipsis is kind of important,
though: "...and decided to determine which header files were missing
their own necessary #include's and forward declarations." The way I
did so was making a simple one-line .c file that included exactly one
header, and checked to see if I could compile it (without any special
defines), fixed it up as necessary, then repeated that process for
every toplevel header.
Most of the stdlib.h additions were for the definition of size_t,
sha1dc/sha1.h was no different; without my patch:
In file included from nukeme.c:1:0:
sha1dc/sha1.h:96:43: error: unknown type name ‘size_t’
void SHA1DCUpdate(SHA1_CTX*, const char*, size_t);
Your point that we use SHA1DC_NO_STANDARD_INCLUDES normally when
compiling within git, though, does mean my patch #7 is kind of useless

I never said git or its subprojects failed to compile. I said when I
added another #include of some header to some existing or new files, I
sometimes saw unknown symbol errors. It's happened before, it
happened again today, and I got annoyed, so I set out to address it.
Sorry if that wasn't clear.
