Thanks for your patch! The illumos already defined the following macros.

$ gcc -dM -E - </dev/null | grep -e 'illumos' -e 'sun'
#define __sun 1
#define __illumos__ 1
#define sun 1
#define __sun__ 1

Maybe use the __illumos__ macro more accurity.

+#elif defined(WAIT_USE_EPOLL) && defined(HAVE_SYS_SIGNALFD_H) && \
+ !defined(__sun__)
