This is a problem with upstream.
See this discussion: https://sourcforge.net/p/sdcc/discussion/1865/thread/519e0553fb/
And this bug https://sourceforge.net/p/sdcc/bugs/3714/

Things are working again by me finding a 32-bit zlib1.dll on the interwebs and putting it in the packages/toolchain-sdcc/bin directory.

Judging by the discussion, it may be a minute before they get around to fixing the build, if ever.
