Dear R Development Team,

   I compile R-1.9.1 on AIX 5.2 under 2.9-aix51-020209, and xlf 7.1. In
order to let R compile successfully under gcc 2.9, I have to change one
C statement of file(RHOME//src/modules/X11/devX11.c) line 1768 from
"retrun FALSE" to "retrun NULL", following is C code snapshot:


newX11Desc * Rf_allocNewX11DeviceDesc(double ps)


    newX11Desc *xd;

    /* allocate new device description */

    if (!(xd = (newX11Desc*)calloc(1, sizeof(newX11Desc))))

        return NULL;


    /* From here on, if we need to bail out with "error", */

    /* then we must also free(xd). */


    /*  Font will load at first use.  */


    if (ps < 6 || ps > 24) ps = 12;

    xd->fontface = -1;

    xd->fontsize = -1;

    xd->basefontface = 1;

    xd->basefontsize = ps;

    xd->handleOwnEvents = FALSE;

    xd->window = (Window) NULL;





However I got core dump while I try to use plot() from R:

Making links in per-session dir ...

If /usr/bin/netscape is already running, it is *not* restarted, and

    you must switch to its window.

Otherwise, be patient ...

> x <- rnorm(50)

> y <- rnorm(x)

> plot(x,y)

Illegal instruction (core dumped)



Can anyone give me some suggestion? Thanks!
