Done.

GCC documents -G for shared libraries, and people have been using that for
years. But it's probably not worth figuring this out since -shared is
clearly preferred.

Hmm, that's an interesting effect.

Nope. ;-)

1. in src/interfaces/odbc/GNUmakefile, change
SHLIB_LINK = $(filter -lm, $(LIBS))
to
SHLIB_LINK = $(filter -lm -lnsl -lsocket, $(LIBS))
2. in src/Makefile.shlib, change
LINK.shared = $(COMPILER) -G
into
ifndef cplusplus
ifeq ($(GCC), yes)
LINK.shared = $(CC) -shared
else
LINK.shared = $(CC) -G
endif
else
ifeq ($(GXX), yes)
LINK.shared = $(CXX) -shared
else
LINK.shared = $(CXX) -G
endif
endif
(Or just change the -G if you don't care about generality.)
