You shouldn't expect those to help.LD_LIBRARY_PATH is for finding shared 
libraries at run time. As far as I know, LIBRARY_PATH doesn't do anything.

Libraries defining symbols must come after objects using them. Something 
like this should work, which also takes care of readline's dependency on 
pdcurses:

    i686-pc-mingw32-gcc -Wall -Wextra -g -o vote.exe vote.c -lsqlite3 
-lreadline -lpdcurses
