I had to make the following change in
postgresql-7.3-1/src/include/optimizer/cost.h

extern DLLIMPORT double cpu_index_tuple_cost;
//extern double cpu_index_tuple_cost;

when I compliled PostGIS against 7-3.1 which you can grab here
http://www.vso.cape.com/~nhv/files/postgres/cygPostGIS_731.tgz

YMMV but I think that this will work fine with 7-3.2
