Hi Martin,

Sure, I can improve sanity checking.


Thanks!

What exactly have you screwed up?

I had, in lang.opt

EnumValue
Enum (gfc_fcoarray) String (native) Value (GFC_FCOARRAY_NATIVE)

It was a bit non-obvious to me that this led to the whole sub-option
being ignored due to

*drum roll*

the space between the keywords and the opening parenthesis.  I have
internalized the GNU style guides to such an extent that I hardly
ever see the space there :-)

Regards

	Thomas
