   Thanks Florian van Michael,

You can find the files I changed on
      http://fwn06.housing.rug.nl/fpc-stm32f4
There you find the above files, the Makefile.fpc from rtl/embedded and
the new files in rtl/embedded/arm.

The diff from cpuinfo.pas with current trunk is:

Looks alright to me.

Also ok?
I think the error has to come from one of these files, not the contents of the rtl itself.
The rtl code is still rather rough, but it compiles.

   That would be nice,
