I was trying to compile 8.2beta3 on openbsd, and ran into an interesting
issue. My account on the particular openbsd box has some restrictive
ulimit settings, so I don't have a lot of memory to work with. I was
getting an out of memory issue linking postgres, while I did not before.
I figured out that the -g flag was being surreptitiously added to my
CFLAGS. It was like pulling teeth trying to get the -g flag out. I tried
--disable-debug to configure, which did not work. I had to do
CFLAGS=-O2 ./configure ...
Is this a known feature in the betas to get people running with -g in case
things break, or is this a configure bug, or expected?
Here is the first bit from configure, note the -g in the using CFLAGS line
at the end.

It's odd, and a little unsettling, to reflect upon the fact that
English is the only major language in which "I" is capitalized; in many
other languages "You" is capitalized and the "i" is lower case. -- Sydney J. Harris
