I'm nonplussed. To obviate any effect from Basic 1.5 and my menu, I 
built a boot disk with just ProDOS 2.0.3, loader.system from the the 
"contrib" folder at <ftp://ftp.musoftware.de/pub/uz/cc65/>, and this 
test code compiled with a recent build of cc65 V2.12.0:

<http://sites.google.com/site/trashgod/Home/p1.po>

#include <conio.h>
#include <stdio.h>
#include <stdlib.h>
#include <time.h>

/* Assume 80-column card, ProDOS, Basic */
void col80() {
    __asm__ ("jsr %w", 0xc300);
    __asm__ ("lda %b", 0x36);
    __asm__ ("sta %w", 0xbe30);
    __asm__ ("lda %b", 0x37);
    __asm__ ("sta %w", 0xbe31);
    __asm__ ("lda %b", 0x38);
    __asm__ ("sta %w", 0xbe32);
    __asm__ ("lda %b", 0x39);
    __asm__ ("sta %w", 0xbe33);
}

int main (void) {

    time_t starttime = time(NULL);
    time_t endtime = time(NULL);

    col80();

    printf("Start time: %s\n",asctime(localtime(&starttime)));
    printf("  End time: %s\n",asctime(localtime(&endtime)));
    printf("Done!  Press any key to exit.");
    cgetc();

    return EXIT_SUCCESS;
}
