Heh. Maybe not dead, but certainly not really alive either ;-) Given the
evidence in your patch that clearly 8.3 isn't quite up to speed on
cygwin, and nobody has really noticed until now.

Good!

I assume this is a WIP and not actually for application, right? Please
look it over because it contains a number of pure-whitespace changes
that make it harder to read, and that will just end up being undone by
pgindent at a later date anyway.

I also notice this in auth.c:
+#ifdef·__CYGWIN__
+#define·WIN32
+#endif

What is the need to change this for just one file? Seems very fragile -
the rest of our codebase assumes WIN32 != CYGWIN, and I think we should
keep that consistent.


There's also a number of:
-#ifndef·WIN32
+#if·!defined(WIN32)·||·defined(__CYGWIN__)

If I read that right, it shouldn't be necessary as long as the WIN32
define is not set on CYGWIN?


And finally:
-············VALUE·"OriginalFilename",·"libpq.dll\0"
+············VALUE·"OriginalFilename",·"cygpq.dll\0"

This obviously has to be done another way, because that change will
affect the win32 platform as well...
