Please also add the following to Makefile.

else ifeq ($(shell uname), FreeBSD)
    include Makefile.freebsd

[tbuktu]

Thank you!

[textbrowser]

Per https://www.freebsd.org/cgi/man.cgi?query=byteorder&sektion=9 and https://www.freebsd.org/doc/en/books/porters-handbook/porting-versions.html, please prepare poly.c as follows. Will test as soon as possible. I may have changes if the build fails.

#ifdef __FreeBSD__
#if __FreeBSD__ >= 5
#include <sys/endian.h>
#else
#define htole64(x) (x)
#define htole32(x) (x)
#endif
#endif

[textbrowser]

All set. Thanks.

I'm not sure anyone uses FreeBSD < 5 anymore because it was released ages ago.
