Compilation errors?

I was trying to build pgsql code, and I keep getting this error:

make[4]: Entering directory `/home/dima/postgres7.3/pgsql/src/interfaces/ecpg/preproc'
make -C ../../../../src/port all
make[5]: Entering directory `/home/dima/postgres7.3/pgsql/src/port'
make[5]: Nothing to be done for `all'.
make[5]: Leaving directory `/home/dima/postgres7.3/pgsql/src/port'
bison -y -d  preproc.y
preproc.y:5560: fatal error: maximum table size (32767) exceeded
make[4]: *** [preproc.h] Error 1


I was building the CVS tip initially when I got this, then I switched to REL7_3_STABLE, but I am still getting the same
problemwith it? 

Any clues? Is it something wrong with my configuration?

I'll appreciate your help with this

Thanks a lot!
