Feliz Páscoa a todos !!!
Consegui compilar e usar a lib do firebird com o Harbour do SVN...
Agora, desejo compliar a mesma lib com o Harbour que acompanha a MiniGUI, e criei o .bat com o conteudo abaixo:

@echo off
PATH=C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;c:\minigui\Harbour\Bin;c:\Borland\Bcc55\bin;c:\Minigui\batch
SET LIB=C:\MINIGUI\LIB;C:\Minigui\HARBOUR\LIB;C:\BORLAND\bCC55\LIB;C:\Firebird\lib
SET INCLUDE=C:\MINIGUI\INCLUDE;C:\Minigui\HARBOUR\INCLUDE;C:\BORLAND\bCC55\INCLUDE;C:\Firebird\include
SET LIB=%LIB%;c:\Bcc55\lib;c:\Minigui\Harbour\lib;C:\Minigui\Lib
SET HB_PATH=C:\minigui\HARBOUR
SET MG_CMP=HARBOUR
SET HB_PLATFORM=win
@echo on

hbmk2 -inc -hblib -hbfbird tfirebrd.prg

C:\MiniGUI\SOURCE\hbfbird>compilar

C:\MiniGUI\SOURCE\hbfbird>hbmk2 -inc -hblib -hbfbird tfirebrd.prg
hbmk2: Processing environment options: -platform=win
hbmk2: Compiling Harbour sources...
Error F0034 Bad command line option 'f'
hbmk2: Error: Running Harbour compiler (embedded). 1
(c:\minigui\Harbour\Bin\harbour.exe) -n1 tfirebrd.prg -hbfbird -o.hbmk\win\bcc\
-ic:\minigui\Harbour\include -undef:.ARCH. -D__PLATFORM__WINDOWS -D__LITTLE_ENDI
AN__ -D__ARCH32BIT__
C:\MiniGUI\SOURCE\hbfbird>

O que pode estar provocando o erro ?
Alguém teria uma dica ?

Será que esse hbmk2 da Minigui não é customizado ? com os .BAT que vem com a Minigui não pra compilar ?
