I do have $(HOME)/local/powerpc-ibm-eabi/bin/ar.exe
and I am using $(HOME)/local/bin/xar.exe for my stuff here, after install.
To bootstrap, GCC may better use $(HOME)/local/powerpc-ibm-eabi/bin/ar.exe

Well, sometimes you are sure the field is 8 bits wide,
limit_msb is only 4 bits unlike base_msb.
A value does not fit the size would be better, but ...

In your Testcase without the unnecessary enum, the u = def; is compiled as:

The number of writes for that volatile structure may or may not be a problem,
I am more concerned by the number of reads of some memory which may not be
readable at all.
