[En-Nut-Discussion] Different automatically generated build trees in Linux and Windows for NutOS 4.8 (was Re: "US_PIOA_PINS_A" redefined)

[José Vallet]

OK, going forward.

The problem seems to the version of nutconf that I was using. It seems 
that somehow version 1.4.3 was generating the build tree wrongly for me. 
I have tried now with versions 2.0.5 and 2.0.9, and they both work.

I am still surprised. Has there been any significant changes between 
versions so that this can happen? Does this mean that something has 
changed in the .nut and .conf files so that they require nutconf version 2?

Regards
José
