Blind Compiler - A Blindfolded Compiler Is Useless
The Compiler is blind for a clearly present header file. This is unacceptable in 2016. In 1985 there were compilers who were strikt, clear and obvious and absolutely logic. Where are they today???
I sure want a liberating answer or a ‘thank you’ for finding a bug because yes this is more like a bug than a configuration problem. If it is a configuration problem then the technology is seriously going awry. There is no reason something should be an added ‘configuration’ to make a compiler see the obviously present file. It really beats me these days how unnecessary complicated thing have become for a straightforward job. Unbelievable.
Of course this is board independent. The issue is straightforward about blindness to clearly visible tree incorporated files.
