If you can find out which file is the problem, we can probably fix it
without access to the machine.

You can compile everything with -O2, then change your optimization in
Makefile.custom to -O0.  Go to psql/src/backend and 'cd' to a directory,
do a 'make clean', then a make,make install and test initdb.  As soon as
it starts working, you have your directory.  Or you could compile
everything with -O0 and start doing -O2 compiles until it breaks.

When you find the directory, find the file by recompiling one at a time.
Once you find the file, I think I can figure out what is wrong with the
file.  I can go through the diff since 6.3.2, and see what has changed.
