i was going to put it in toys.h initially, but it seemed (from the
comments on each block) like toys.h was only meant for _standard_
headers?  <getopt.h> is a non-standard (but common to BSD, glibc,
bionic, macOS) header that defines the non-standard *long* getopt
functions. the POSIX getopt() function is in <unistd.h>.

if you add a "non-standard but everyone has them" block to toys.h i'll
put any similar future cases there :-)
