And finally... A version of helloWorld that works.

/* workaround for ROM globals placed at the start of the .data / .bss area; we need to shift out own variables past them */
__attribute__((section(".romglobals"))) int __ROMglobals__[20]={0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};

int main()
{
hpg_set_mode_mono(1);
hpg_set_font(HPG_STDSCREEN, hpg_get_minifont());
hpg_clear();
hpg_draw_text("Hello, world!", 0, 0);
hpg_flip(); //updates the screen with the new image (needed in double-buffered mode)
WAIT_CANCEL;
return 0;
}

A bit of a long way round, with a misleading example on the HPGCC3 web-site, but real signs of life.
Thanks a lot for your help.

Cheers
