Ok, I found another thing: With your patch, co65 outputs (for example)

   PP_READWRITE_DATA = +16384

ca65 does not accept this line

   1571.s(8): Error: Syntax error
   1571.s(8): Error: Unexpected trailing garbage characters

removing the "+" for decimal solves this problem.

According to ca65-3.html#ss3.3, ca65 does not expect a plus sign for a
decimal number, so I believe this would be a bug in co65, not in ca65.
But I may be wrong. ;-) BTW: Does ca65 support negative values?

Ok. As you already know, I am not interested in Lunix, but in the
1541/1571/1581 drives with (x)o65 files. Do you recommend another better
option? ld65-5.html#ss5.8 does not mention if other OS versions than
Lunix are supported. http://www.6502.org/users/andre/o65/fileformat.html
mentions the OSA/65 header supplement, and you told me that there is a
version for cc65 use. But which keywords do I have to use for this? And
is it recommended to try another variant?

Anyway, now, I can link o65 files together to form an executable (after
removing the "+" from the .s files generated from co65).

BTW: To compile the cc65 package on my cygwin box [1], I had to make
sure that src/common/inttypes.h includes stdint.h instead of defining
the own types, or I get an error.

Trying to check for __STDC_VERSION__ with a simple test source [2], I
get "No __STDC_VERSION__", so I do not know how this can be
distinguished.

Anything, everything else compiles flawlessly (despite the docs, but I
do not have the sgml tools installed).

Regards,
   Spiro.

    int main(void)
    {
    #ifdef __STDC_VERSION__
        printf("%s\n", #__STDC_VERSION__);
    #else
        printf("NO _STDC_VERSION_\n");
    #endif
        return 0;
    }
