But <unistd.h> is not supposed to declare select() in POSIX: see
  http://www.opengroup.org/onlinepubs/009695399/functions/select.html
POSIX says <sys/select.h> should declare it. <unistd.h> is unrelated.

Since gnulib's policy is to let the programs write code in POSIX syntax, I vote
for a module that creates a <sys/select.h> file in the build directory. On
most platforms it would need to include <sys/time.h> too; on Woe32 it would use
<winsock.h>. full-header-path.m4 comes in handy here.
