We have the following warning on Windows:
pgarch.c:349: warning: implicit declaration of function `sleep'
To fix it we could include the right header (which appears to be
<stdlib.h> in the Windows/Mingw case), or we could replace the call by a
call to pg_usleep().
I'm inclined to do the latter, on grounds of consistency, but want to be
sure that it will get the signal handling right.
Unless I hear squawks of objection I will supply a patch for that soon.
cheers
