Postgres 7.2-3 --with-tcl from source

Please, can anybody explain me how ...the hell... to compile Postgres 7.2 from source --with-tcl option. My steps  (according to read from forums) were :

1.
ln -s /bin/cygtclsh80.exe /bin/tclsh
ln -s /bin/cygwish80.exe /bin/wish

2.Add manually -lcygtcl83 to DLLLIBS in "/src/makefiles/Makefile.win".Now my DLLLIBS looks like this: DLLLIBS= -L/usr/local/lib -lcygipc -lcrypt -lcygtcl83

3. go to /src/pl/tcl and run make.

make produces "makefile.tcldefs" .I'd read that "Makefile" needs the TCL_SHARED_BUILD = 1 from that file.

4. return to /usr/src/postgresql-7.2.3 and run configure than make.make does well until it goes to build pltcl.When compiling pltcl.c compiler gives me many "undefined reference" errors and then obviously fails:

pltcl.o(.text+0x14):pltcl.c: undefined reference to `_TopMemoryContext'
pltcl.o(.text+0x1d):pltcl.c: undefined reference to `_fmgr_info_cxt'

I've no idea what this all about.  If these bugs are fixed in new Postgres7.3 source,I'd better will go to compile PostgreSQL 7.3 from source.If not -please, help me.I completely tired to find why ... the hell... --with-tcl won't compile.

Any help would be very appreciated.
