That test is now done. The only tests that fail are those involving
timezones.
The build and test was not that smooth. Overall I'd recommend
upgrading to Cygwin 1.1.4 or later rather than applying all the fixes
needed for B20.1.
I revised Jason's patches for two of the files. My attached patch is
against the original 7.0.2 code. Jason's patch should be edited to
remove the sections for backend/utils/error/elog.c and exc.c. His
patch was posted to PORTS on Tue, 26 Sep 2000 15:21:46 -0400.
This patch is for 7.0.2. I am sending a patch to do the same thing
for 7.1 to the PATCHES mailing list. It works around the lack of
sys_nerr on Cygwin B20.1 and BeOS. More details on pgsql-patches.
