But if the overload with the "psem_t" is removed the "var" variant 
doesn't compile either:

=== output begin ===

Free Pascal Compiler version 2.6.0 [2011/12/23] for i386
Copyright (c) 1993-2011 by Florian Klaempfl and others
Target OS: Linux for i386
Compiling vartest.pas
vartest.pas(22,14) Error: Can't assign values to an address
vartest.pas(24) Fatal: There were 1 errors compiling module, stopping
Fatal: Compilation aborted
Error: /mnt/data/applications/fpc/2.6.0/bin/ppc386 returned an error 
exitcode (normal if you did not specify a source file to be compiled)

=== output end ===

So my personal opinion is still that this is a bug...
