Given the above, I'm willing to rip out the sys_nerr stuff in elog.c and
exc.c but I'm afraid of breaking other platforms. Please advise.

I presume that you really meant "os.h" instead of "port.h" above.

I will reiterate that Cygnus (a.k.a Red Hat) has stated that they no
longer support b20.1 anymore. They are actually seeking out mirrors
with the old releases and requesting that they be deleted. It will
become harder and harder to find b20.1 soon...

Can I assume that dllinit.c is only used by Cygwin (i.e, not by straight
Win32)? If so, then I can surround the contents with:
#if CYGWIN_VERSION_DLL_MAJOR < 1001
#endif /* CYGWIN_VERSION_DLL_MAJOR */
Otherwise, this part of the patch is going to get ugly.
I will resubmit my patch after the above issues are resolved.
