I think the patch itself is OK, but it's not clear how the old #include
would cause this error. The current make infrastructure builds with
-I<...>/libflash, so the current '#include <ecc.h>' would include this file.

[Also, you don't get an error about a missing include file, so the old
#include must be hitting something else]

Could you include the commit you're building from here, and check the
preprocessor output to find out which ecc.h is being included? Is there
a stale ecc.h in your tree?

Thanks,


Jeremy
