Danke! Seems to work with the snapshot. BTW. Had some problems  
compiling the snapshot but I recalled the "make zap" vs. "make clean"  
discussion not so long ago and did make zap before remaking... Now  
only get some warnings here and there, like:

assertion.c:46: warning: unused parameter 'A'
and
ar65: Warning: Replacing module `systime.o' by older version

but I take them to be harmless.

One more question though. To test this new feature I adapted a test  
proggy:
//***************************************************
#include <stdio.h>
#include <stdlib.h>

int main (void)
{
	FILE *fh;
	unsigned char byte_from_file;
	fh = fopen("testfile","ro");
	while (!feof(fh))
	{
		byte_from_file = fgetc(fh);
		fputc(byte_from_file, stdout);
	}
	fclose(fh);
	exit(EXIT_SUCCESS);
}
//***************************************************

Should something as simple as the above work? It doesn't seem to.  
Target is C64 so the IO should be there, right?
