I have inspected the environment variable path as follows (for
readability I have replaced ; with CRLF so each path item will be on a
separate line):

In ControlPanel the System path is:

C:\Programs\Tcl\bin
C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\
C:\Programs\Borland\BDS\4.0\Bin
C:\Programs\Python\.
C:\Programs\Borland\Delphi7\Bin
C:\Programs\Borland\Delphi7\Projects\Bpl\
%SystemRoot%\system32
%SystemRoot%
%SystemRoot%\System32\Wbem
C:\Program Files\Microsoft SQL Server\80\Tools\BINN
C:\Program Files\Borland\CaliberRM SDK 2005 R2\lib
c:\Program Files\Microsoft SQL Server\90\Tools\binn\
C:\Programs\ULTRAE~1
C:\Programs\Microchip\MPLAB IDE\VDI
C:\Programs\GnuPG
C:\Program Files\IVI Foundation\VISA\WinNT\Bin\
C:\Program Files\IVI Foundation\VISA\WinNT\Bin
C:\Programs\TortoiseSVN\bin
C:\Programs\Subversion\bin
C:\Programs\lazarus\fpc\2.4.2\bin\i386-Win32

And user path is:

C:\Programs\Utils
C:\Documents and Settings\Bosse\My Documents\Borland Studio
Projects\Bpl
C:\Programs\CVSNT\
C:\Programs\QT\4.4.3\bin

When I start a new command window and type PATH into it:

C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\
C:\Programs\Borland\BDS\4.0\Bin
C:\Programs\Python\.
C:\Programs\Borland\Delphi7\Bin
C:\Programs\Borland\Delphi7\Projects\Bpl\
C:\WINDOWS\system32
C:\WINDOWS
C:\WINDOWS\System32\Wbem
C:\Program Files\Microsoft SQL Server\80\Tools\BINN
C:\Program Files\Borland\CaliberRM SDK 2005 R2\lib
c:\Program Files\Microsoft SQL Server\90\Tools\binn\
C:\Programs\ULTRAE~1
C:\Programs\Microchip\MPLAB IDE\VDI
C:\Programs\GnuPG
C:\Program Files\IVI Foundation\VISA\WinNT\Bin\
C:\Program Files\IVI Foundation\VISA\WinNT\Bin
C:\Programs\TortoiseSVN\bin
C:\Programs\Subversion\bin
C:\Programs\Utils
C:\Documents and Settings\Bosse\My Documents\Borland Studio
Projects\Bpl
C:\Programs\CVSNT\
C:\Programs\QT\4.4.3\bin

As you can see in the active path there is no sign of FPC, but I have
not restarted after installing FPC...

------------ Restarting test PC --------

And here is the output of path after restart:

C:\Programs\Tcl\bin
C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\
C:\Programs\Borland\BDS\4.0\Bin
C:\Programs\Python\.
C:\Programs\Borland\Delphi7\Bin
C:\Programs\Borland\Delphi7\Projects\Bpl\
C:\WINDOWS\system32
C:\WINDOWS
C:\WINDOWS\System32\Wbem
C:\Program Files\Microsoft SQL Server\80\Tools\BINN
C:\Program Files\Borland\CaliberRM SDK 2005 R2\lib
c:\Program Files\Microsoft SQL Server\90\Tools\binn\
C:\Programs\ULTRAE~1
C:\Programs\Microchip\MPLAB IDE\VDI
C:\Programs\GnuPG
C:\Program Files\IVI Foundation\VISA\WinNT\Bin\
C:\Program Files\IVI Foundation\VISA\WinNT\Bin
C:\Programs\TortoiseSVN\bin
C:\Programs\Subversion\bin
C:\Programs\lazarus\fpc\2.4.2\bin\i386-Win32
C:\Programs\Utils
C:\Documents and Settings\Bosse\My Documents\Borland Studio
Projects\Bpl
C:\Programs\CVSNT\
C:\Programs\QT\4.4.3\bin

Now two items have been added:
C:\Programs\Tcl\bin
C:\Programs\lazarus\fpc\2.4.2\bin\i386-Win32

Yes, I guess that would be the case if make.exe changes the current
dir when it starts. 

But the strange thing in that case is that the lazaus makefile resides
in the directory where I invoked the command so how does make find it
if it changes the current dir?

I had a look at the makefile and searched for FPC and located a
section where it goes to extensive lengths to find the FPC compiler!

Anyways I repeated my compilation now with the extra FPC argument
added (all on one line of course):

C:\Programs\lazarus\fpc\2.4.2\bin\i386-win32\make.exe clean all
FPC=C:\Programs\lazarus\fpc\2.4.2\bin\i386-win32\fpc.exe

At the end there was this error:

Compiling lazconfigstorage.pas
lresources.pp(5320,13) Error: Incompatible types: got "AnsiString"
expected "Char"
lresources.pp(5514) Fatal: There were 1 errors compiling module,
stopping
Fatal: Compilation aborted

I guess I have to get the dev snapshot of lazarus sources to get
around this?
