 It looks like it's trying to redefine the standard `memmove` function. The
 project's build system has code that's supposed to determine whether the
 system has a standard `memmove` function; that determination might not be
 working correctly in this case.

 If this were a normal autotools project we would look for implicit
 declaration of function errors in the config.log but this project does not
 use autotools and does not have a config.log so I'm not sure if the errors
 are saved anywhere for us to look at.

 The determination of `memmove` availability is made using the source file
 have_memmv.c. In that file I see that it is trying to use the function
 `memmove` but does not have the line `#include <string.h>` which is where
 that function is defined. Adding that line to that file may help, but
 there may be other tests that need similar fixes.

 It looks like we could get the build system to disable quiet mode and thus
 maybe see the results of running these tests by adding `Q=` to the build
 args.

 A new version of calc is available. We should probably start by updating
 to that version and see if that improves the situation.
