Problems with win32 patch/build

I am working my way through getting the postgres win32 port (7.2.1)
compiled under MSVC. I got through the patch and the compilation, but
am having problems with the linker. Trying to link the backend, I get
43 linker errors like:
unresolved external symbol GUC-scanstr
unresolved external symbol ProcessConfigFile
unresolved external symbol num_columns_read
unresolved external symbol Int_yychar

These symbols are listed in the postgres.def file. Removing them
removes the errors. If I do so, I get a new set of errors:

Linking...
Creating library ..\..\Debug/postgres.lib and object
..\..\Debug/postgres.exp
postmaster.obj : error LNK2001: unresolved external symbol
_ProcessConfigFile
bootstrap.lib(bootstrap.obj) : error LNK2001: unresolved external

symbol

_ProcessConfigFile
tcop.lib(postgres.obj) : error LNK2001: unresolved external symbol
_ProcessConfigFile
bootstrap.lib(bootstrap.obj) : error LNK2001: unresolved external

symbol

_Int_yyparse
..\..\Debug\backend.dll : fatal error LNK1120: 2 unresolved externals
Error executing link.exe

Also, when trying to compile ecpg, I get
flex: could not create '.\preproc\pgc.c'

There were some weird things that went on during my first compile run
that I fixed as I went and I'm afraid I broke something. Any
suggestions?

If I can get through this I'll start hitting patch #2 and start

running

tests versus 7.3.x source.

I think I figured it out. lexx has a problem with the guc_file.l. I
should be able to tackle that: sorry to pester.
