Building psql.exe using the free Borland compiler

Has anybody succeeded in building psql from 8.1.3 using bcc55? I've got
everything going OK up to the final link stage at which point I get

ilink32.exe @MAKE0000.@@@
Turbo Incremental Link 5.00 Copyright (c) 1997, 2000 Borland
Error: Unresolved external '_pclose' referenced from
C:\USR\SRC\POSTGRES\POSTGRESQL-8.1.3\SRC\BIN\PSQL\RELEASE\EXEC.OBJ

with a similar error for _popen. I'm using a source tree which has compiled OK
under Linux to save the hassle of making sure I have a working perl/flex on the
Windows system, have made sure that it's using pg_config.h.win32, and can see
blibpq.dll being rebuilt. I've got an ilink32.cfg file containing
-L"c:\usr\local\Bcc55\lib" where this directory contains cw32mti.lib etc.

Apologies if this is a really dumb question. I don't /do/ C/C++ on Windows, I'm
much more a bare-metal guy who does Delphi and Perl when he needs high-level.
