 pngcrush fails to build. The fatal error is:

 {{{
 :info:build In file included from pngcrush.c:1709:
 :info:build In file included from ./png.c:14:
 :info:build ./pngpriv.h:518:16: fatal error: 'fp.h' file not found
 :info:build   518 | #      include <fp.h>
 :info:build       |                ^~~~~~
 }}}

 Judging by clues found in a web search, this seems to be an
 incompatibility in an old version of libpng that seems to be embedded in
 the pngcrush sources. Perhaps it is feasible to patch.
