other multibyte encodings.  Per prior discussion.

Also, revert my earlier change to move installation path mashing from
Makefile.global to configure.  Turns out not to work well because configure
script is working with unexpanded variables, and so fails to match in
cases where it should match.

some more port modules, but they are easily added.

of installation paths during configure, rather than every time Makefile.global
is read.

to find another solution (probably similar to the way libpq does it).

Add Win32 code to look in the current directory before the path.

Add code so memory is allocated using palloc in backend object files.

Remove elog() calls from find_my_exec;  do fprintf(stderr) instead.  We
can then remove the exec.c handling in the makefile because it doesn't
have to be built to suppress elog calls.

Create new get_* functions to access compiled-in paths and adjust if
relative installs are to be used.

Clean up substitute_libpath_macro() code.
