Dear Tom,I have removed the NO_MKTIME_BEFORE_1970 symbol from irix5.h,
rebuilt 7.3b2, and reran the regression. The three time tests
(tinterval, horology, abstime) now match the Solaris expected files.I checked the timezone files, and the system does
notappear to
have savings time defined for 1947, but it does report it as such
in the PostgreSQL regression tests.WRT your old message about the mktime workaround, I must have
missed your message. However, in the future, if you want something
tested on Irix, please let me know. I use PostgreSQL a fair amount at
Bristol-Myers Squibb, and I will spend some time to keep it working.
Sincerely, Bob
