However this sentence should continue, I've tried the following: 1. reconstructed the original cprt0.as 2. recompiled fpc-2.0.4 release sources 3. added "-Xf" to my .fpc.cfg 4. tried a complete compile of lazarus and a testing program of mine But sadly I were not successful, the only error I get is the same as before, initializing tls fails: <compiling lazarus> $ gmake clean all ...

How can I go on from here, should I try switching startup code again and try "-Xd"?
