Well.  IMHO (after looking into it) the CURRENT_TIME has no business
of being in ipc.h in the first place.  Here follows a patch that moves
it into a private header file of cygwin32_ipc.

As the seems to
be the "official" (only) place of cygwin32_ipc, it should be easy to
push a next version or something. Or to include the patch with postgresql.

If this is wrong, I can look what should be done to PostgreSQL about it.

BTW, about doc/README.NT: There is a line:
> 12. Initdb --username=jkr (do not run this command as administrator)

but initdb does not have option --username ...
Also there is a patch attached (for cygwin32_ipc, it seems), but nothing said
what should be done about it.
