Here is a patch that is incremental to the previous patch and makes AIX
not use DST before 1970. The results are now consistent with other
no-DST-before-1970 platforms.
The down side is, that I did not do a configure test, and did not incooperate
IRIX, since I didn't know what define to check.
The correct thing to do instead of the #if defined (_AIX) would be to use
something like #ifdef NO_NEGATIVE_MKTIME and set that with a configure.
Thomas, are you volunteering ?
