Yes, the only problem is that they are not OLEDB as Delphi has the unit.
Probably more ADO like.

It seems that oledb itself has no typelib, at least I can't find it (scanned all files in 
common\ado and common\ole db), and others hint on it too
( http://www.gocher.me/ADO-Free-Pascal )

So manual conversion of the (huge) SDK header is the only way out it seems.

--------------------------
Final batch file:

del *.pas *.lpk *.ppu *.o

set inputdir="%CommonProgramFiles(x86)%\system\ado" 
set lazdir=d:\repo\lazarus
set outputdir=c:\tlbs

echo from %inputdir% to %outputdir%

set flags=-a -d "%outputdir%" -p
mkdir %outputdir%
cd /d %inputdir%
rem  for /r %%i in (*.tlb) do importtl %flags% "%%i"

set inputdir="%CommonProgramFiles(x86)%\system\ole db"

cd /d %inputdir%
for /r %%i in (*.dll) do importtl %flags% "%%i"

cd %outputdir%

rem assumes lazarus compiled and activex component installed, flags on one
line.

# rem on one line
set flags=-Fu%lazdir%\components\activex\lib\i386-win32 
              -Fu%lazdir%\lcl\units\i386-win32
                    -Fu%lazdir%\components\lazutils\lib\i386-win32

for /r %%i in (*_tlb.pas) do fpc %flags% "%%i"
