There's a patch attached to fix gcc 2.8.x warnings, except for the

yyerror ones from bison. It also includes a few 'enhancements' to
the C programming style (which are, of course, personal).

The other patch removes the compilation of backend/lib/qsort.c, as
qsort() is a standard function in stdlib.h and can be used any
where else (and it is). It was only used in
backend/optimizer/geqo/geqo_pool.c, backend/optimizer/path/predmig.c,
and backend/storage/page/bufpage.c

There's more to come. Please review these patches. I ran the
regression tests and they only failed where this was expected
(random, geo, etc).

Cheers,
