[x] Done. :-)

I did some research and submitted a patch to diet libc, the only other
issue that I had with PostgreSQL was a minor one, which I fixed with a
small patch to PostgreSQL:

http://synflood.at/patches/pgsql-diet.diff

The first fix is that PostgreSQL relies on that, when reading the output
of postgres -V, all the output can be read with a single read call (or
whatever call is used, it comes down to read(2) in the end) when called
from initdb. This is not the case with diet libc, as the puts
implementation in diet libc does two write calls, with the second write
call happening with a closed pipe. Changing the puts to printf removes
this problem, optionally you could change the format string to "%s\n" to
get the original output (although the patch doesn't break PostgreSQL
w/o diet libc, AFAICS).

The other modifications in src/timezone/data/europe are a quick fix
because I got the error message "line too long" when trying to do a make
install.
