Double defined Symbol Warning

[xXorAa]

xtc68 issues these warnings where it probably should not.

test.txt

Attached a test program, the compiled version of which works as it prints 2 3 when run so the symbols are not actually overwriting each other like the warning would indicate.

qcc -o test-c68 test.c
Double defined Symbol: _ONE
test-c68: dataspace 870 (366)
Multiply defined :        1

The warning is valid; historically, QDOS/c68 uses upper case for SROFF XDEF tokens.
The attached is a slightly less trivial example. It may not behave as you expect as the symbol is imported once.
Given the historical aspect (and all libc XDEFs are upper case), I'm minded not to remove the warning.

I see what you mean. That is a gotcha when porting C stuff to QL.

I guess we leave this issue open so the next time someone stumbles on it they know what is going on!

And in the original single compilation unit case, if you do the "right" thing and define the variables as static; then the problem also goes away.

That is a gotcha when porting C stuff to QL.

Indeed, as is the fact that C68 is so old, ANSI C only.
