snapshot and FreeBSD-2.2.7 not building

The blizzard hitting the Chicago area makes today ideal for hacking -
as long as the power stays on! A thousand pardons if this is a known
problem - I'm just getting started with the current CVS set.

I grabbed postgresql.snapshot.tar.gz for 8 am, Jan 2 and am trying to
build it on my FreeBSD-2.2.7 system in order to test some things for
the web site. This seems to be the only source kit available from
hub's anonymous FTP archive, BTW.

Here's what happens:

...
gmake[2]: Entering directory `/pgsql-src/pgsql/src/backend/utils'
for i in adt cache error fmgr hash init misc mmgr sort time; do gmake -C $i SUBSYS.o; done
gmake[3]: Entering directory `/pgsql-src/pgsql/src/backend/utils/adt'

gmake[1]: *** [utils.dir] Error 2
gmake[1]: Leaving directory `/pgsql-src/pgsql/src/backend'
gmake: *** [all] Error 2

I think the compiler is right in claiming incompatible types. In rev
1.3 of backend/utils/adt/numeric.c, line 1783 says

*result = num;

but "result" is a float32 (=*float), while "num" is Numeric (pointer
to a custom PostgreSQL NumericData struct). What is intended here?
