[avr-libc-dev] [HEAD/1.0] Commit: fix for bug #9669

[Joerg Wunsch]

I just fixed the FAQ entry explaining the use of ROM tables.

Since people (including the originator of the entry :) occasionally
stumble across it, I also mentioned the special case where the index
into a ROM table is compile-time constant, so the compiler would
optimize the access, thereby hiding the bug that the pointer should be
extracted from ROM using memcpy_P().  (Usually, people use that fixed
index case as a proof-of-concept test, and then later crash when
trying to make it based on a variable.)
