Just in case anyone else stumbles over this: misc/rhash fails to build on Solaris 11.3 with

gcc calc_sums.o hash_print.o common_func.o hash_update.o file.o file_mask.o file_set.o find_file.o hash_check.o output.o parse_cmdline.o rhash_main.o win_utils.o librhash/librhash.so.0  -L/opt/pkg-hrz/20191004/lib -Wl,-R/opt/pkg-hrz/20191004/lib -L/opt/pkg-hrz/20191004/lib -Wl,-R/opt/pkg-hrz/20191004/lib -lintl -o rhash
Undefined                       first referenced
 symbol                             in file
aligned_alloc                       librhash/librhash.so.0

None of the substitutes in librhash/util.h is selected - or would work, as far as I can see.

The package will probably build on Solaris 11.4, as stdlib there provides this function.
