1) adds NetBSD shared lib support on both ELF and a.out platforms
2) replaces "-L$(LIBPQDIR) -lpq" with "$(LIBPQ)" defined in
Makefile.global. This makes it much easier to build stuff in
the source tree after you've already installed the libraries.
3) adds TEMPLATEDIR in Makefile.global that indicates where the
database templates are stored. This separates the template files
from real libraries that are installed in $(LIBDIR).
4) changes include order of <readline/readline.h> and <readline.h>.
The latest GNU readline installs its headers under a readline
subdirectory.
In addition to applying the patch below the following files need to be copied:
backend/port/dynloader:
bsd.h -> netbsd.h
bsd.c -> netbsd.c
include/port:
bsd.h -> netbsd.h
makefiles:
Makefile.bsd -> Makefile.netbsd
It would be great to see this incorporated into the source tree before
the 7.0 release is cut.
Thanks!
