Problem solved..
The LCD.C and LCD.H files I've been using are NOT part of the WinAVR
distribution!
This is my work PC, used by others, and someone switched out the fine coffee
normally served in this restaurant with Folger's Crystals.. Let's watch.
:-P
Sorry for the confusion..

[...char vs. signed cahr vs. unsigned char...]
Don't look it up - if you learn the compiler's default behaviour, you
risk writing incorrect code. If it is in any way relevant whether a
char is signed or not, write signed char or unsigned char explicitly

I am still very puzzled over why the compiler balks wether I use signed or
unsigned chars to feed lcd_puts.
When I used unsigned char it balked. When I used char, it didn't.
Now when I use int8_t or uint8_t, it balks.

I know what *I* am missing - the source code! How is anyone supposed to
help you with your problem until you post the actual compilable code
snippet? We need a compilable code sample which demonstrates the problem,

That would work. Another way is to have get_key return int.
Oops. I mean, of course, make key an int. Having get_key return an int that
is then stored into a char would accomplish... nothing.

Correction: The routine in question is lcd_putc not lcd_puts.

Dave, I have two recommendations for a beginner at C.

I learned to code C/C++ with the dummies book, it gave pretty clear
examples.
C doesn't have to be hard, just take the time to grock it and not
rush it.
Also, this is a great read for understanding social dynamics on how to
ask people questions and get an answer.

That's true in C, but C++ considers all three as separate types (C++
is a little bit fussier about mixing types).
C99 does as well, but it doesn't enforce it in a strict way. An
application making assumptions about the signedness of the type char
