Not sure why or when this started happening, but for whatever reason gcc does not consider libraries specified before the object files when linking; previously this was being generated:

gcc  -g -O2 -lfq -lfbclient -lreadline -lm  -o fbsql main.o common.o input.o inputloop.o tab-complete.o command.o command_test.o query.o strlcpy.o pgstrcasecmp.o fbsqlscan.o

Fixed so it builds with this invocation:

gcc  -g -O2   -o fbsql main.o common.o input.o inputloop.o tab-complete.o command.o command_test.o query.o strlcpy.o pgstrcasecmp.o fbsqlscan.o -lfq -lfbclient -lreadline -lm

Thanks, @ibarwick ! fbsql works fine. I'm going to debug https://github.com/ibarwick/fbsql/issues/1. Now there is only some code-style warnings like https://github.com/ibarwick/fbsql/issues/4.
