Problem using HSI on STM32

Hi!

I am (again) proting a project to NutO/S and (again) it is based on
STM32. While starting to move the project, I tried to start a simple
demo code on the existing hardware using STM32F1 DISCOVERY as a base.

Unfortunately I cannot configure anything to work on STM32F1 internal
HSI by selecting the appropriate settings in qnutconf.

I thought it should work with:
System clock source = SYSCLK_PLL
PLL Clock Source = PLLCLK_HSI

All other settings left as default.

The compile fails with several misconfigured defines, I attached the
compile output at the end.
I hopefully upgraded to the latest repository code but I am truly out
of using SVN I use the git svn commands for now.

I wonder about the fact, that when I initially loaded the
f1_discovery.nut the Device tree was missing and no MPU was selected.
I had to click the F103 to get the missing selections.

kind regards
Ulrich
